Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

the primary geometric control for the astronauts descriptions and
samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen

Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

the primary geometric control for the astronauts descriptions and
samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time

Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

the primary geometric control for the astronauts descriptions and
samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

LSelf-contained power source
Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

Proportion of mass and power assigned to scientific payload is uncertain
along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

along an astronauts traverse The staff incorporates instruments
that are best utilized at eye level or at the end of a probe Other
subsystems of the field exploration system will support or enhance
the function of the surveying staff
Staff Television Camera
Scientific functions--The staff television camera will obtain
the images that constitute the prime geological record of the dis-
tribution and surficial nature of the materials at the landing site
Combined with the staff tracking and orientation data the images
also contain the information needed for the photogrammetric and
photometric compilation of a large scale topographic map of the
landing site The surface geometry and photometric properties por-
trayed by the television imagery will include a far greater number
of features than the astronaut will find possible to observe and
describe
General subsystem specifications-- The staff television camera
will take and transmit every few seconds a high resolution image of
features along the astronaut traverse A vidicon camera similar
in genera1 performance to the Ranger F cameras meets the scientific
and performance requirements for the surveying staff television
camera The general specifications for the combined camera and
transmitter subsystem are as follows
1) Vidicon tube diameter 112 to 314 inch active scan area and complementary optical system to give $80 or more TV resolution lines
2) Frame transmission time of about 15 seeonds
3) Cycle repetition rate of 5 seconds or less includ- ing erase and prepare time
4) Equal horizontal and vertical resolution
5) Exposure time of 5 milliseconds or less with shutter speed uniform to within 1 percen
6) Depth of focus of 05 m to 25 m or greater
7) Tube scene luminance response of 5 to 2500 foot lamberts
8) Separate sun sensor with the same spectral response and field of view as the vidicon tube for control of a servo iris
9 ) Automatic shutter inhibitor driven off of sun sensor to prevent exposure of vidicon tube to direct sunlight
10) 1 1 aspect ratio of image format
11) Image format scribed to define the raster
12) Reseau marks to define the image geometry
13) 500 Kc bandwidth allocation for real time transmission on the S-band transponder
L4) VWF video relay transmitter incorporated into the staff and compatible with other subsystem telemetry requirements
15) VHF video receiver in LEN that is compatible with retransmission on the S-band transponder
161 Active andlor passive environmental control
17) Induced external electrical and magnetic fields of subsystem compatible with unimpaired operation of other sub systems
18) Shape and volume compatible with staff concept
19) Directional hand grip on staff for rough pointing oi camera
20) Power requirement of 20 watts or less
21) Weight of camera and transmitter 5 kg or less
Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

Stereometric Film Camera
Scientific functions-- Detailed physical dimensions color and
photometric properties of selected features and surficial materials
within about 6 meters of the astronaut will be ob+ained from images
taken by a stereometric film camera The images will permit photo-
grammetric colorimetric and photometric analysis of small parts
of the ~oons surface determined by the astronaut to be of special
interest The accurately known base line of the camera also pro-
vides a means of obtaining supplementary control for the photogram-
metric reduction of staff television imagery Color composite
photographs will be prepared from selected images for post-mission
interpretation

the primary geometric control for the astronauts descriptions and
samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

the primary geometric control for the astronauts descriptions and
samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

samples and for data acquired by the physical properties module
- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

- - A hybrid radio and optical
tracking subsystem can fulfill the above functions but consideration
should also be given to the development of a fully optical system
Either will require components both in the staff and in the LEM
The general specifications for a hybrid radio-optical tracking sub-
system are as follows
1) RF ranging from 10 to 500 m with an accuracy of + 03 me-2) RE (100 Me) transmitter on LEN with a maximum mass of
15 kg and a maximum power reqniwment of about 2C watts
3 ) RF transponder on the staff with a maxim~~mmass of 09 kg and a maximum power requirement of about 05 watts Shape and volume compatible with staff concept
4 ) Optical azimuth and vertical angle determination (utilizing monochromatic transmitting and receiving diodes at LEM and corner reflectors on s t a f f ) to an accuracy of If 34 minutes of arc or better
5) Optical components (scanning mirrors gimbals lenses motors and servo-amplifiers) oa LEM with maximum mass of 5 5 kg and a power requirement of about 73 watts
6 ) Automatic reacquisition of surveying staff if line of sight is temporarily lost
7) Subsystem compatible with integration into drive for surveillance subsystem to provide automatic visual and television tracking through periscope
8) Telemetry requirements compatible With surveillance subsystem VHF video tramsmitter
9) Readout rate of one sample per second or greater
10) Active andor passive environmental control
11) Induced external electric and magnetic fields of system compatible with unimpaired operation of other staff and LEM subsystems
Scientific functions-- The staff orientation subsystem will
automatically transmit the tip tilt and pointing azimuth of the
staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store

staff at least once a second and in synchronization with the shutters
on the staff cameras Each angular reading will be made to an accuracy
of -+ 1 minute to permit precise photogrammetric compilation of the images obtained by the cameras
-- The scientific functions of
the surveying staff orientation system can be ace~aplishedby an array
of photocell sensors on a sun compass and a vertical meter that meas-
ures tip and tilt relative to the local gravity vector It also will
be possible to develop gyroscopic orientaticn subsystem if operational
considerations indicate its desirability The general functional
specifications for a subsystem that includes a s~~ncompass are as
follows
1) Tip and tilt from 9 90 to -90C + 1 minute 2) Azimuth (uncorrected) from a sun compass from 0 to
360 + 1 minute-3) Correction (on Earth) of azimuth for tip and tilt
of sun compass
4 ) Sun compass vertical meter and telemetry encoder to have a maximum weight of 03 kg and a maximum power requirement of about 3 watts
5) Shape and volume compatible with incorporation into head of surveying staff
6) Telemetry requirements compatible with staff VBP video transmitter
7) Readout rate of one sample per second or greater
8) Active andor passive environmental eontrsl
9) Induced external electric and magnetic fields of subsystem compatible with unimpaired operation of other staff subsystems
Auxiliary orientation instruments
Scientific functions-- The incorporation of visual readout of
the staff orientation data or of simple auxiliary surveying instru-
ments into the surveying staff will increase the flexibility of the
astronauts investigations The readout capabilities of the auxiliary
instruments will enable the astronaut to obtain and mentally store
