INTRODUCTION

1.1 HUMAN FACTORS ENGINEERING EFFORT

This report is a description of the Human Factors Engineering effort

on Special Programs and Program 461 for the year 1962.

The human engineering effort, in compliance with MIL-STD-803 (USAF)

"Human Engineering Criteria for Aircraft, Missile, and Space Systems

Ground Support Equipment", dated 5 November 1959, consisted of a program( to determine the operability and maintainability requirements of the

system and individual equipment at VTS, NHS, and NPS.

The human engineering program comprised the following activities:

a. Human Factors Engineering assistance to equipment designers

was provided in implementing changes and recommending or

specifying hardware characteristics for control display equipment.

In support of this effort, control display off-the-shelf hardware

was evaluated to insure adequacy of hardware in meeting MIL-STD-803

requirements.

b. Proposed field modifications and engineering change orders were

reviewed to determine adequacy of design, to provide a basis

for modification of equipment or procedure, and to recommend

remedial actions.

c. Station activities, control display design, and layout of work

areas were monitored and evaluated to determine the adequacy of

equipment and work areas in meeting operability objectives.

d. Field communication requirements and modifications were

reviewed and revised to meet increased network loading. Problem

areas and deficiencies which could degrade system effectiveness

and require timely corrective action were identified.

e. System requirement studies were participated in to determine

the flow and form of information and the decisions and actions

for maintenance and operations. Feasible alternative ways for

using human being and man-equipment combinations to meet System

requirements were determined.

INSTRUMENTATION AT NHS FOR PROGRAM 698BJ

2.1 HUMAN ENGINEERING DESCRIPTION

This study describes and analyzes the major man-machine inter-

actions within the New Hampshire Station (NHS) during Program 698BJ

prepass, orbit, and postorbit operations. The utilization of sub-

systems and equipment, including new support equipment peculiar to

Program 698BJ, at NHS is also described. The major control and display

consoles and their interface equipment are described in detail.

Console panel drawings were developed with a tabular listing of

control display hardware, nomenclature, recommended vendor, function,

[and signal source. The flow of operations in terms of operator decision

action sequences were also diagrammed for the consOlel positions. VoIce

Icommunications required to support operations and maintenance were dis-cussed, and diagrams were developed to illustrate who talks to whom

I: during the various phases of station activity.

The conclusion of the study included human engineering evaluations

and recommendations. This study is being published separately.

INSTRUMENTATION FORVTS"AND NHS TRACKING AND DATA CONSOLES

4.1 INTRODUCTION

J This report consolidates the Human Factors Engineering design

inputs for the Tracking and Data (T&D) consoles for Vandenberg Tracking

j Station (VTS) and New Hampshire Station (NHS). These inputs consist

of panel layouts, cabinet configurations, panel hardware function lists,

and operator decision/action flow diagrams.

The task of Human Engineering was to ensure that the console was

designed for maximum operability with minimum chance for error. This

was accomplished by studying the entire Tracking and Data system to

determine the required control and display functions of the console by

utilizing established psychological and physiological design principles

and by conforming to the contractually binding Human Engineering design

standard MIL-STD-803 (USAF).

The T&D consoles are the central control and monitoring locations

for the 60-foot multipurpose antennas (formerly called the Data Receiving,

or. D/R, antennas) modified by WDL Technical Directives 156 (VTS) and

157 (NHS), Revision 2. According to Revision 2, the T&D antenna is

I capable of the following functions:

a. Receive on the 2.2-2.3 Gc band,

b. Receive on the 400 Mc band,

c. Receive on the 225-245 Mc band,

d. Doppler transmit on the 375 Mc band,

e. Command transmit on the 1.7-1.85 Gc band (less transmitter),I

IPHIe.L C WESTMIN OEVNLOPNENT LBNTR9

WDL-TR2007

f. Autotrack on the 2.2-2.3 Gc band, and

g. Autotrack on the 400 Mc band.

in addition, it is possible to manually track signals in the 225-245 Mc

band. Before the modification, the only function of the antenna was

to receive on the 2.2-2.3 Gc band. However, at present, the only

functions added to the tracking stations were according to Revision 1

of the modification. These were the range rate and autotrack capabilities Iof the two-way 400 Mc Doppler system. Some of the reasons why the

modifications were made are:

a. To simplify the tracking station by reducing the amount of

equipment, while retaining all the station ca-pabilities,

b. To take advantage of the high gain and accuracy of the T&D

antenna,

c. To accomplish the research and development necessary to 1provide multipurpose antennas for future systems,

d. To reduce the number of personnel, while maintaining the load

capability of the station, I

e. To increase the station reliability by reducing the amount Iof equipment,

f. To provide back-up for existing facilities, and

g. To simplify administration, checkout, and operating procedures. LA block diagram of the Multipurpose Antenna Subsystems is shown

in Fig. 4-1. The diagram illustrates the relationship of the T&D console

to the Multipurpose Subsystems. The antenna drive, boresight equipment, HDoppler system, and UHF receivers are controlled and monitored for the

T&D console. 4"2

4.2 GENERAL DESCRIPTION OF CONSOLE

4.2.1 Console Configuration

The T&D console is made up of four bays in line (Figs. 4-2 and

4-3). It is intended to be operated by two people: the antenna I

controller at the left three bays, and the RF operator at the right

bay. The console is located in the Data Receiver (D/R) buildings at 4VTS and NHS. The consoles are identical at both sites, except for the

inclusion of a television boresight display and a wind speed indicator

on the VTS console. At the time this report was written, a work order

had not been issued for the RF panel; consequently, the information

pertaining to it in this report is not to be regarded as final.

4.2.2 Console Functions

The console is designed to provide the operators with the

capability of accomplishing large-loop equipment readiness checks and

most of the required during-pass control and monitoring functions.

The equipment, which is partially controlled and monitored to carry

out these functions, includes the antenna system, boresight transmitters,

Doppler system, UHF tracking receivers, and VHF receivers. Each of

these equipment systems is described in the following section. 1

4.2.3 Console-Controlled Equipment

The following paragraphs describe the equipment associated with

the T&D console. The five equipment areas are the antenna drive,

boresight equipment, T&D receivers, Doppler system and VHF receivers.

Antenna Drive

The antenna drive system within the T&D building is composed

of intermediate and power servos for each antenna axis. The positioning

of the azimuth, transverse, and declination intermediate servos

ultimately results in the antenna axes assuming the corresponding

positions. The signal sources for the positioning of the intermediate

servos are

c. Digital-to-analog converters (DACON's),

d. Search scan generator, and

e. Tracking receivers.

f The console rate controls (Fig. 4-4) and the remote rate

controls generate voltages proportional in amplitude to the sine of

the displacement from their center null positions. These voltages

are applied to the intermediate servos when the console is in the mode.

Console information and status are provided on the display panel(Fig. 4-5).

The outputs of the DACON's are applied to the power servos

I when the antenna is in the SLAVED or BORESIGHT mode. The voltages

are proportional in amplitude to the difference between the desired and

f actual antenna positions. The desired antenna position information is

accepted from a remote source when the antenna is in the SLAVED mode

and from the control panel in the ASDE rack when in the BORESIGHT mode.

Servo error is displayed on the servo panel (Fig. 4-6).

When the'antenna is in the SEARCH mode,'theintermediate

servos accept information from the search scan generator. The width

frate and inclination of the bar scan are selected at the console.t When the antenna is in the AUTOTRACK mode, the selected

tracking receiver supplies the error voltages to the intermediate

servos. The tracking receiver is selected on the RF panel of the

console (Fig. 4-7).

At the time this report was written, two sets of servo

equipment existed in the D/R building, one of which is required for the

self-track capability. A switch in the cablehead rack selects the

set of servo equipment to be enabled.

Boresight Equipment

The dial control on the Boresight panel (Figs. 4-8 and 4-9)

provides the antenna operator with control of several transmitter

functions in the near field and far field boresight towers. By

dialing an appropriate number, control is provided for any of the

boresight transmitters, with selection of various frequencies and atten-

uation levels. Also, control is provided to turn on the optical targets,

the PAM simulatorand control of the T&D antenna-mounted boresight

equipment.

When a number is dialed, a pulse train is routed to the

Boresight Control Rack, OA-53. The pulse train is decoded at OA-53 and

routed to its proper destination to accomplish the desired control

action. The Near Field Rack, OA-118, or Far Field Rack No. 1, OA-55,

receives the signal from the Boresight Control Rack and converts it

to a control voltage. This voltage is applied to the proper equipment

to accomplish the desired control action. A verification signal is

sent back to the Boresight panel to emergize the legend light corresponding

to the completed control action.

The outputs of the selected UHF receiver and the PAM

simulator can be displayed on the two-gun oscilloscope in the boresight

bay of the console. By displaying the output of the PAM simulator on

one gun and the output of the UHF or VHF receiver on the other gun,

the test signal can be compared before it is sent to the boresight

transmitters and after it is received by the T&D antenna receiver.

The antenna controller has sufficient controls and informa-

tion displayed on the console to conduct confidence checks of both

I the antenna columniation and the quality of the received signal.

Tracking and Data Receiver

The two Tracking and Data (T&D) receivers recover the 2.2-

2.3 Gc PAM data from the satellite. They will also supply tracking

error Voltages to the antenna servo system for the autotrack function

j when Revision 2 of the modification is implemented.

{Figure 4-10 is a simplified block diagram of the T&D receivers.It shows that the incoming signal is amplified by preamp 1 or preamp 2

depending upon which is chosen by the T&D console operator. (See Fig.

4-11 for the tracking procedure.) The signal passes through a filter

and is routed to both T&D receivers by a hybird coaxial junction. After

[the signal is converted to 5 Mc, it passes through the selectablebandpass filters and is then available for routing to the DAP building

[for processing and to the tracking converter for conversion to trackingerror voltages. The receiver supplying the signal for these purposes

is selected at the RF panel. The 5 Mc signal from both receivers

is limited, detected, amplified, and displayed on a spectrum analyzer at

the same time for comparison..

Figure 4-12 is a flow diagram showing the interaction

Ibetween the voltage-controlled oscillator (VCO) statuses and theantenna modes for one receiver. The five VCO statuses are as

[follows:

Search - The VCO automatically sweeps the receiver tuning

about a center frequency at a rate of approximately 10 cps.

IHold - If the receiver detects a signal between the -104

and -94 dbm levels, the VCO will leave the "search" status and enter the

_"hold" status. It will remain in the "hold" status for approximately

3 seconds, even if the received signal is lost. if the signal persists,

the VCO will remain in the "hold" status for approximately 1 minute.

in this status, the VCO keeps the receiver tuned to the frequency at

which the signal was first detected. At the end of 1 minute, the VCO

will enter the "search" status, make partial sweep, and re-enter the

"hold" status in less than 0.1 second. if the received signal falls

j below the -104 dbm level, the VCO will return to the "search" status.

If the signal increases above the -94 dbm level, the VCO will enter

the "AFC' status.

AFC - The received signal must be avove the -94 dbma level

for the VCO to be in the "AFC" status. In this status, the VCO

continually tunes the receiver to the frequency of the incoming signal.

When either VCO is in the "AFC" status, the "UHF OPERATING" light

corresponding to that receiver will be energized on the RF panel.

Manual - When the VCO is in the "manual" mode, it can be

I" tuned manually.

- Signal Loss - If the received signal falls below the -94

dbm level, the VCO will enter the "signal loss" status for 3 seconds,

then enter the "search" status. In the "signal loss" status, the VCO

remains tuned to the same frequency at which the signal was lost.

Doppler System

The main components of the Doppler system are the 375 Mc

I transmitter, the 400 Mc receiver, and the 4-element monopulse feedhorn.

The transmitter is located in equipment rack OA-119 and the receiver

f in equipment rack OA-79.

The transmitter transmits a highly stable frequency to the

satellite. The satellite accurately upconverts the frequency by a

constant amount and transmits a return frequency to the ground station.

I+ The ground receiver detects the return frequency and extracts its rate

-4-19

PIILCO W. D E R

WDL-TR2007

of change due to the Doppler shift. From the rate of change of the

received frequency and the angular position of the antenna, the satellite

ephemerides can be calculated. Besides extracting the Doppler data

from the vehicle signal. The Doppler receiver provides tracking

error voltages to the antenna intermediate servos for autotrack 7]purposes.

The satellite signal is received through the hybird

monopulse feedhorn, then divided between the azimuth, elevation, and Ireference channels of the receiver (Fig. 4-13). Each channel is

identical up the 4.5 Mc i-f amplifiers. The VCO, which is tuned by the

phase lock loop during signal tracking, provides the mixing frequency

to the mixers to keep the input to the i-f amplifiers at exactly 4.5 IMc. The Doppler extractor takes its input from the VCO to provide

range rate information. Figure 4-13 shows where the console control

and display points were selected on the basis of their usefulness

during a pass. Prepass operations, such as calibrating, peaking, etc.,

were functions to be performed by the rack technician. The console Ioperation of the Doppler system is diagrammed in Fig. 4-14, and the

layout of the console panel from which the Doppler system is controlled Iis shown in Fig. 4-7.

.The primary tasks of the Doppler system operator are to I

a. Ensure that the Doppler transmitter output is routed to 3the antenna feedhorn and is of proper strength,

b. Ensure that the VCO is frequency-searching before ETA

reaches zero,

c. Select the proper tracking receiver (UHF or Doppler),

and,

d. Restart the VCO sweep after a monentary signal loss Uduring a pass.

VHF Receivers

The console displays relating to the VHF receivers are

the NOT READY, READY, and OPERATING status lights and the VHF signal

strength meter. The'console has no control over the VHF receivers.

The signal source for both the status lights and the signal strength

meter is a control panel in VHF receiver rack OA-78. The VHF rack

technician will continually appraise the status (NOT READY, READY,

or OPERATING) of each of the five receivers and will select a switch

position on the control panel for the corresponding status. This

will energize the appropriate status lights on both the T&D console

and the master control console.

During a pass, the VHF signal strength meter on the T&D

console is used as a manual tracking display. The antenna controller

can keep the meter "peaked" by manipulating the rate controls in

f- order to drive the antenna in the proper direction.

The choice of the VHF receiver to supply the meter on the

console is made by the VHF rack technician. It is his task to select

the best signal and to select a switch position on the control panel

for the appropriate receiver. This will route the signal strength of the

-2 best receiver to the console.

4.3.2 Console Operation

The following flow diagrams (Figs. 4-15 through 4-18) describe

how the console operators will utilize the panel controls and displays

in order to carry out the various antenna system functions:

"Console Turn-On and Prepass Readiness Sequence";

"Prepass Preparation, Antenna Controller";"B-oresight Lens Focus Sequence, Antenna Controller"; and

"Lock-on Test, Antenna Controller".

The strongest concentration of attention is on anticipated

contingency situations in which the console operators must become

aware of the nature of the contingency and make a corresponding

recovery response.

The flow diagrams were generated as a paradigm and consequently

are not to be construed as final operating procedures. Detailed

operating procedures can be found in the following WDL documents:

VTS WDL-TM-SA-911-4 (Data Receiving Function Manual) "

WDL-TM-SA-302-3 (Field Maintenance Manual)

NBTS WDL-TM-SA-925-4 (Organizational Maintenance Manual) :1WDL-TM-SA-310-3 (Field Maintenance Manual) :

4.4 REQUIRED COMMUNICATION NETWORK MODIFICATIONS

The modification of the Data Reveiving antenna required the ]addition of fourteen equipment cabinets and a T&D console to the

D/R buildings at each station. The new equipment created the

requirement for additional communication facilities.

The design recommendations made by Human Factors Engineering for

the additional communication equipment were based upon the following

considerations of the operators and their functions:

a. The necessity for information not available through equipment

displays or face-to-face contact with other operators,

b. The requirement of certain operators to provide status information,

c. The requirement of certain operators to exert or respond to

command or administrative authority , and

d. The optimum location of communication facilities for easy

access by the operators using them.

With these considerations in mind, Human Facotrs personnel

participated in establishing the new communication networks and the

panel and jack locations. Figure 4-19 shows the original design

input made by Human Facotrs. WDL drawing E113942 is, in part, a

result of this work.

Communication panel locations in the new equipment can be deter-

mined from WDL drawings E108934 (Communications Space Allocation,

UHF T/D Rcvr. Bldg. SS/H Van); C97-132595 (Elevation Drawing, Front,

Frequency Converter, OA-57); C97-132596 (Elevation Drawing, Front, Xmtr.,

Near Field, Boresight Equipment, OA-118); and C97-132594 (Elevation

Drawing, Front, Xmtr., Test Checkout & Calibration, 375 Mc, Normal Channel,

OA-120).

In addition to the new communication panels and jack outlets,

other changes included in relocation of two jack boxes in the antenna

support structure and outer rim of the dish.I-

SECTION 5

SURVEY OF INTER- AND INTRA-STATIONCOMMUNICATIONS

5.1 INTRODUCTION

The communications data gathering was first conducted at VTS, then

at NHS, and finally at ATS. The VTS and NHS evaluations were conducted

primarily to observe the integration of the existing communication equip-

ment with the required operational tasks.

The ATS communication analysis was requested by the Test Wing and

is a part of the Human Factors Engineering (HFE) requirement.

The ATS communication analysistherefore, is, included in this

report as one of HFE's past-year activities.

Since the communication subsystem is one of the most vital links

of any operation, requirements for evaluating other stations still

exist and are being planned for the coming year. The stations to be

visited include NPS, TTS, HTS, and IOS.

5.2 VTS COMMUNICATIONS

The comments pertaining to the VTS portion of this communication

report were made only in reference to the communication equipment of

the master console room and the equipment room of the D.A.P. building.

Data sheets (see Figs. 5-1 and 5-2) were prepared prior to the

station visit and were filled out at the station as a means of gatheringand retaining information. The following comments are based upon

observations, personal interviews with equipment and console operators,

and information on the data sheets.

5.2.1 VTS Communication Equipment

The communication equipment at VTS was not standardized in any

way. Seven different types of communication panels, ranging from

recorder panels to jack outlets for the plotboards, existed in the Jmaster console and equipment rooms. jack outlets in back of the

communication panels (maintenance jack outlets) differed in type from

the operational jack outlets in front of the panels. The maintenance

jack outlets were never used because headsets with the male type jacks

required for the maintenance jack outlets could not be obtained. As a

result, the maintenance operations in the back of the racks were

conducted with front panel headsets by stretching the phone cords over

the top or around the side of the racks.

5.2.2 VTS Communication Equipment Locations

In general, the communication equipment locations were good, but

could have been better. At two of the operational positions, the

operator had to walk about 25 to 30 feet before having access to a dial

phone. In another instance, the communication control panel was 50 feet

from the operating position auxiliary jack outlet.

The rack locations for the communication equipment had been

placed in areas other than those recommended by Human Factors Engineering.

The rack communication panel should have remained in the recommended

areas. In one case, the utility shelf was positioned right below the

communication panel: test equipment placed on that shelf obscured the

entire communication panel.

5.2.3 VTS Communication Net -Configuration

The net configuration for VTS consisted of 21 nets: 8 operational

nets including all stations, 12 nets divided into maintenance and check-

out groups, and 1 back-up net including all the operational stations.

It was the feeling of the Communications Officer that the maintenance

and checkout nets should be kept separate from the operational nets.

Further, the maintenance and checkout nets were never to be used for

operational nets.

5-4

PHILCO WESTERN DEVRLOPMENT LABORATORIES

VTS has unique net requirements because launch facilities are

incorpprated into the operational net configuration. Other stations do

not have this launch communication requirement; therefore, the total

nets for the other stations are less in number.

5.2.4 VTS Communication Panel Hardware

The communication panel hardware was not totally activated,

causing some delays during operational activities. The main difficulty

was caused by the fact that the P.B.X. dial was not put into operation

on most of the communication panels, thereby requiring the operators

to make extra trips to the nearest P.B.X. phones.

Other operational delays were caused by the absence of the "lamp

test" to check the indicator switches and the volume control for the

headsets. There were also incorrectly labeled operational net select

switches and unlabeled rubber-booted toggle switches. The functions of

the latter were completely unknown to the operations personnel.

5.2.5 New VTS Modular Communication Panel

New VTS modular communication panels were being installed in the

control areas. The new panel replaces some of the old Kellog equipment

and facilitates operational procedures.

Figure 5-3 shows the layout of the new communication panel now

installed at VTS. There are two types of 3 in. by 19 in. net select

panels: one for conference "A" and "B", and the other for direct point-

to-point select operation. These two panels must be installed in pairs

in order to achieve the desired operational capability.

The conference "A" position on the panel is used for monitoring,

v" and the conference "B" position is used for talking into the conference

net as well as for monitoring. It should be noted that the conference

"A" and "B" panel can not be used unless a net on the direct point-to-

3 point select panel below it is activated or in use and the facilities

control switch for conference net "A" or "B" is activated.

Each communication panel consists of 15 one-inch modules, each

containing one relay toggle switch, one light indicator, and one AMP

connector in the module rear (Fig. 5-4). Each module is wired as a

different circuit and can be removed from the panel by pulling on the

toggle switch to disengage the AMP connector. The physical size of each

module is 1 in. by 3 in. by 5 in. The indicator light on each module

is split into three sections (Fig. 5-5). Various combinations of lights

denote the utilization of the communication net.

*The 2 in. by 19 in. panel, located at the bottom of the communica-

tion panels, is the control panel for the communication equipment

(Fig. 5-6). The panel houses two jack outlets, a 1/2 in. POWER ON

indicator, a 3/8-in. momentary LAMP TEST pushbutton, eight Micro switches,

and two volume controls. The eight Micro switches on the control panel

are grouped into five switches for FACILITIES CONTROL and three switches

for COMMON CONTROL.

The FACILITIES CONTROL switches consist of two activating switches

for monitoring on conference nets: CONFERENCE A MONITOR and CONFERENCE

" B MONITOR. Three other switches arepresently unassigned.

The three COMMON CONTROL switches consist of the DIAL LINE HEAD-

SET HANDSET TRANSFER switch, the BUZZER CUTOFF switch, and the HOLD

switch. The DIAL LINE HEADSET HANDSET TRANSFER switch transfers

administrative dial calls onto the operational headset. The BUZZER CUT-

OFF switch turns off the audible signal, leaving on only the visual

signal. The HOLD switch holds any incoming administrative calls on the

dial phone until the operator from the operational net is clear.

~i One of the volume controls on the HEADSET control area of the

panel controls the monitor (receiver) volume level, and the other controls

the voice (transmitter) volume level. Both jack outlets for the headset

are the screw-on pin type outlets. One outlet is used continuously forJ operations, and the other is available as an auxiliary jack outlet.

The momentary LAMP TEST pushbutton is used to check all conference

and operational net light indicators. Each conference and operational

net panel combination assigned to a control panel uses the one LAMP TEST

pushbutton. The POWER ON lamp of the control panel indicates when power

is supplied to the communication panels.

The net signalling is automatically activated by switching the

direct net select toggle switch to the talk monitor position. The

signal will remain activated intermittently until the signaled operator

answers the net called. A speaker monitor facility may also accompany

the communication control panel and the set of net and conference

select panels.

5.2.6 Human Factors Engineering Comments

Although the new control area communication panels are installed

to facilitate operational procedures, they fall short of the desired

human engineering approach to design and ease of operation. This new

V panel requires more human action than the simple communication panels

presently being used at other stations (ATS and TTS).

T

- 5.3 NHS COMMUNICATIONS

The comments pertaining to this portion of the report were derived

from an on-station survey of the communication subsystem. Observations,

personal interviews with console and equipment operators, and data sheets

similar to those used at VTS were incorporated in the study.

1 5.3.1 NHS Communication Equipment

The communication equipment used at NHS was standardized, but

not to any great extent. The previous program communication equipment

and the equipment presently being used represented six types of panels

and no (3) net select jackboxes.

7- 5-11


IWDL-TR2007

One of the greatest operational setbacks involved the lack of

monitor speakers on the communication panels. At certain operator

positions, additional dial phones were supplemented to handle additional

administrative calls. The speaker monitors were remote, and the controls

for the monitors were in locations away from the operator's position.

Other items which caused confusion were components such as the

net select release button. The release button would release any one of

the net select buttons activated in the first row of six buttons, but

could not deactivate any one of the net select buttons depressed in the

second or third row. The net select button depressed in the second or

third row could only be deactivated by partially depressing one of the

buttons in the same row.

The line volume level dropped off from time to time; therefore,

the operators in the high ambient noise level areas added transistorized

line amplifiers to their headsets to compensate for the background noise.

As compared with VTS, however, all dial phones on the cominica-

tion panels were activated and all net select buttons were correctly

identified and clearly labeled. Furthermore, the communication jack

outlets in back of the communication panels were of the same type as

those on the front, which enabled the same type of headsets to be used

for operations on either side. Although the public address system was

designed as a ten-zone system, it is used primarily as a one-zone system. I

5.3.2 NHS Communication Equipment Locations

The NHS communication equipment locations were good, but could

be improved. On-station modifications of the equipment locations placed

some of the communications panels in areas not agreeable with good human

engineering practice: on top of the writing shelf of the M.C.C., one

communication panel below the other, jack outlets, 4-1/2 in. off the

floor hidden under a door, and so forth.

5.3.3 NHS Comnunication Net Configuration

The net configuration for NHS consisted of 13 nets, one S.T.C.

hotline, and one special net. During operations, five full nets are in

use for tracking and commanding functions.

The 13 nets are identified as follows:

Since N.H.S. has special project operations going on from time

to time, it was felt that separations were necessary in the net configu-

ration as listed above. If a new program board communication design is

to be used for the future system, five operational nets could easily

handle the whole operational system.

5.3.4 NHS-Comunication Panel Hardware

The NHS communication panel hardware is not the approved military

standard type. The net select pushbutton control surfaces are smaller

than the required control surface diameter stated in Military Standard

803. The same switch is also used to activate the signal "on-off"

function with an additional twisting control motion which is quite

confusing.

A highly desirable component which was not included on any panel

is a "lamp test" pushbutton for checking the indicator lights of all the

net select switches. Several lights were out on the couunication

panels, and it was quite difficult to determine which nets were activated.

Furthermore, unlabeled toggle switches were present in the control

areas, some of which were placed in awkward locations.

5.3.5 NHS Human Factors Engineering Comments

The existing NHS operational communication equipment handles the

operational system adequately, but could be improved by the incorporation

of standardized components and Human-Engineered communication panels. t

Flexibility and adaptability to various operational and admin-

istrative systems were lacking because of the absence of a speaker

monitoring facility on the operational comunication panel.

Additional equipment mounted on the communication panel at a

later date should have been of the same type as the rest of the control

components on the panel, since both types perform the same control

functions.

5-22

PHILC0 WESTERN DEVELOPMENT LAORATORIK8

WDLTR2007

There should have been closer coordination between the manufacturer

and Human Factors Engineering on the design of the communication panels.

An operational communication panel utilizing a new concept in communica-

tion operation is being designed at present for NHS.

5.4 ATS CMMUNICATIONS

The communication subsystem described in the following paragraphs

is presently installed and operating at ATS. The operations described

are typical of the tracking, comnanding, prepass, and postpass functions

of ATS.

The ATS communication survey was conducted in much the same manner

as those for VTS and NHS. However, several exceptions made possible

a more complete analysis of the ATS communication subsystem:

a. More time was spent at ATS

b. Several actual tracking operations were monitored, and

c. Personal interviews were held with all operators.

5.4.1 General Comments

The operational procedures, design, placement, and allocation

I of the communication equipment was far superior at ATS than at NHS or VTS.

The operators were completely satisfied with the communication equipment,

I which had been designed specifically for their operational system.

Although the Human-Engineered communication panels were not manu-

factured with the appearance and hardware recommended by Human Engineer-

ing (Fig. 5-15), the panel produced by the manufacturer (Fig. 5-16)

1. remained the same. As a result, the operational procedures were not

affected in any manner.

The communication panels and the communication jackboxes

(Fig. 5-17) were used to the fullest capacity during prepass, postpass,

and actual operations. All the hardware on the panels and jackboxes

proved to be essential for normal operations. No components on the

Human-Engineered communication panel proved to be unnecessary. On- Istation modifications were made on the control positions requiring extra

operational capabilities with air/ground communications, the S.T.A., and

the antenna pedestals. Figure 5-18 illustrates the communication sub-

system for ATS. 3All communication panels and jackboxes are circuited onto three

operational nets. Although each of the nets are designated for specific

operations, they can be used interchangeably. The third net is used

for maintenance, as a spare for handling special requirements, or as Ia backup in the event the first or second net fails. I

The operators felt that the communication equipment was designed

well enough that the operation of the equipment was self indicative.

As far as the location of the communication equipment is con-

cerned, there were only four places in which allocation of one more

panel and the relocation of two jackboxes and a panel could have

facilitated more efficient operation.

The ATS operational comiunication subsystem consists of the I

following equipment:

13 panels

8 jackboxes

1 air/ground control

3 air/ground Jack outlets

9 sound-powered phones

1 S.T.A. speaker monitor

}_ periods, the ATS operators usually employed the loudspeaker monitor

when working near the communication panels.

The LAMP TEST pushbutton enables a quick check of all light

indicators on the panel. it is usually employed during a prepass check-

out prior to the first orbit operation.

Headset-Jack-Outlets

Two HEADSET Jack outlets are connected in parallel on the

communication panel and on the jackbox. The signal gain is adjusted by

the HEADSET VOL. control. Another jack outlet is provided on the back

of the panel for maintenance, alignment, and calibration purposes.

Additional jack outlets connected in parallel with those on existing

tion, and backup net and is used by certain tracking and comnanding jjpositions during prepass and checkout operations. When special require-

ments are added onto the checkout or fly-by tasks, net 3 is used.--

The PABX pushbutton indicator is used for activating the

dial phone. Pressing the PABX pushbutton indicator automatically

disengages any one of the other four pushbuttons and permits the

operator to dial local interstation or intrastation numbers. Headsets Uare used with the panel PASX dials.

The HOLD pushbutton indicator is used to hold any incoming

PABX calls on the outside line without interfering with the operational

net in use. The HOLD pushbutton will remain activated until the PABX

pushbutton is pressed. The PABX pushbutton is the only switch which

will deactivate the HOLD pushbutton.

Mike indicator

The MIKE indicator lights to show that the microphone of

the panel is "on" and transmission is taking place. The MIKE indicator

was designed primarily to prevent any open mike conditions. At ATS mike

buttons for the headsets have frequently stuck and remained open after

normal transmission.

Signal Pushbutton

The signal pushbutton is used for alerting individuals on

jthe selected net with both an audio and visual signal. At ATS, the

signal button is put to another use: the station controller uses it,

) at ETA-45, to alert all the operators in the transmitting and receiving

areas at the start of the prepass checkout.

Headset Volume Control

The HEADSET VOL. control adjusts the signal output level

for the headsets.

PABX Dial

The PABX dial is used in conjunction with the PABX pushbutton

j indicator for dialing any local station or outside numbers. In comparison

to VTS, much time was saved and extra operations were eliminated from

the ATS tracking personnel activities because the PABX dials were

activated on all the ATS communication panels. Local outside calls are

made by dialing "9" and the outside number. This can be done from any

PABX dial phone. Conference calls are made by dialing "81" on the PABX

dial phone. A maximum of four persons plus the operator on the operator's

turret may dial into the conference call from any dial phone on the station.

5.4.3 Net Select Jackbox

The net select jackbox, shown in Fig. 5-17, has limited capabilities

in comparison to the conunication panel. The jackboxes were placed in

operational positions which did not require the flexibility and capa-

bilities of the communication panel. The hardware mounted on the Jack-

box consists of the following items:

3 net select pushbutton indicators

1 volume control

2 headset jack outlets

1 "mike" indicator light

5.4.4 lublic Address System

The public address (P.A.) system at ATS is a two-zone system

(Fig. 5-26). It is activated by dialing "86" from any station PABX dial

phone or through the station controller's operational P.A. access panel.

The P.A. capability through the access panel overrides the dial-on P.A.

capability. The dial-on capability ("86") puts the P.A. system on an

entire single-zone system and combines both the tracking and receiving

area P.A. nets. The P.A. system loudspeakers are in various locations

of both the transmitting and receiving areas, as indicated in Figs. 5-19

through 5-26.

5.4.5 Public Address Access Panel

The public address access panel (Fig. 5-27), located in the Iconsole bay between the comand controller bay and the station controller

ten-zone systems. The ATS two-zone (plus combination of both zones)

system has eliminated much of the unnecessary hardware and controls found

on both NHS and VTS P.A. access panels.

Mike Jack Plugs

ji The mike jack plugs are the connecting points for the micro-

phone to the P.A. speaker system.

Speaker Test Pushbutton

The SPKR TEST pushbutton is used to check the P.A. speakers

located in both the transmitting and receiving areas. The speakers are

tested with the transmission of a high frequency sound over the P.A.

system.

P.A. Net Select

The three P.A. NET SELECT pushbuttons are used for selecting

the area in which the station controller desires to activate the P.A.

system.

Net 1 is used to activate the P.A. system in the transmitting

area. Net 2 is used to activate the P.A. system in the receiving area.

Net 1 and 2 is used to activate the P.A. system in both the transmitting

and receiving areas.

Teletype/Voice Toggle Switch

The TELETYPE/VOICE toggle switch is used for directing the

use of the alternate teletype/voice circuit. This circuit is one of the

cormunication links between S.T.A. and ATS and is used for sending

teletype tracking data, receiving acquisition messages, or conveying

verbal messages to and from S.T.A.

PABX/Supervisor Telephone-Toggle Switch

The PABX/SUPERVISOR TELEPHONE toggle switch is used for

circuiting the incoming S.T.A. calls onto either the station controller's

headset or the station PABX system.

Hotline Page/Hotline Ring Toggle Switch

The HOTLINE PAGE/HOTLINE RING toggle switch is used for

circuiting the S.T.C. call in parallel to both the transmitting and

receiving area speaker systems. When the toggle switch is switched to

the HOTLINE RING position, it signals the control position at S.T.C.

Hotline Speaker Volume Control

The HOTLINE SPEAKER VOLUME control is used for controlling

the output signal level of the hotline speaker on the van wall in front

of the control console of the A&C van.

Net Speaker Volume Control

The NET SPEAKER VOLUME control is used for controlling the

output signal level of the net speaker.

Fuse Holder

The FUSE holder houses the P.A. access panel fuse.

5.4.6 Operator Turret

The operator turret (Fig. 5-28), placed on top of the overhang

of the amplifier rack in the A&C van, is used as the station PABX switch-

board. The turret houses 70 round indicator switches, 8 twist indicator

switches, 1 PABX dial, and I handset. The switches and dial of the

turret are used as the controls for conferencing, placing long distance

calls, paging, holding, connecting incoming calls into station locals,

monitoring, and switching operator calls into the living area PABX dial

phone during off-duty hours.

The operator's turret should have been located in the communication

van (as previously recommended by Human Factors) instead of in the

congested A&C van.

5.4.7 Sound-Powered Phones

The sound-powered phones, located in various areas (Figs. 5-19,

5-20, 5-21, and 5-25), are used mainly for antenna maintenance, align-

ment, and calibration operations. They are never used for tracking or

commanding operations.

The sound-powered system is divided into two areas: transmitting

and receiving. Each of the independent systems is connected between

the antenna structure, antenna, and their respective controls. The

only operational position having access to both of the sound-powered

nets is located under the overhang of the station controller's console

(Fig. 5-29).

5.4.8 Communication Links

The ATS communication links consist of the following (Fig. 5-30): .

1 Teletype line to S.T.C. (100 wpm)

1 Alternate voice/teletype line to S.T.C. (100 wpm)

1 Air/ground communication (transmit and receive)

100 wpm Teletype

The 100 wpm teletype line sends and receives data to and

from S.T.C. and is used mostly as a date link. The teletype equipment

I which sends this data is an A.S.R. 28 located in the communication van.

Alternate Voice/Te:letype

The alternate voice/teletype line to S.T.C. is also a 100

wpm line. It is used for transmitting and receiving administrative as

well as operational messages. The controlling switch determining the

mode of transmission or reception is located on the Public Address

f access panel (TELETYPE/VOICE toggle switch). When the voice portion of

the alternate voice/teletype system is being used, the transmission and

reception of teletype messages are handled on the second A.S.R. 28 in

the communication van.

Air/Ground Communication

The air/ground communication is conducted over government-

J. furnished equipment (G.F.E.) consisting of AN/GRT 3 and AN/GRR 7

located in the communications van (Fig. 5-23).

The fly-by operations are conducted over the air/ground

fequipment to calibrate and check out ground station telemetry andtracking equipment.

FPABX Long Distance (Long Lines)

The PABX long distance calls are made through Ketchikan.

There are two trunks available for making administrative or operational

calls. These two trunks are also the back-up lines for voice trans-

fmissions to S.T.C. in event the alternate voice/teletype link fails.5.4.9 ATS Communication Equipment Locations

The ATS communication equipment locations were excellent, except

for four locations: three in the radar van and one in the instrumentation

van.

H5E49

PHILCO WESER, EVLPMNTLBOAORE

WDL-TR2007

To satisfy the added requirements for the instrumentation van,

on-station modifications were made by circuiting an additional jack out-

let parallel to the existing communication equipment in the required

area.

Two jackboxes and one communication panel were installed in non-

recommended locations of the radar van. One jackbox was mounted under

the orbital computer console, and the other mounted as the bottom panel

of the timing rack located in the rear of the radar van.

The main communication panel of the radar van was positioned

(after console fabrication) 74 in. above the floor on top of the radar

console, which was the only possible area in which it could have been

mounted. It is impossible for the operator to make any changes in

communication operations from the normal seated operating position.

The jackbox mounted under the orbital computer is recessed, located

12 in. off the van floor, and cannot be seen by a standing operator.

The operation of this jackbox is quite awkward because of the excessive

stooping required to depress the net select button or to plug the head-

set into the jack outlet.

The jackbox mounted as a panel of the timing rack in the rear

of the radar van is in a location only 18 in. off the van floor. At

times, test equipment left on the floor in front of this panel would

completely obscure the three-net select jack panel. A parallel jack

outlet, slaved to this three-net jack panel, is located on the van wall

77 in. off the floor behind the orbital computer. This jack outlet is

used by the orbital computer operator instead of the assigned three-net

jackbox under the orbital computer. The solution to this problem would

be to mount the jackbox on top of the orbital computer (as originally

recommended by Human Factors Engineering).

5-50


WDL-TR2007

The same condition exists for the jackbox mounted on the panel

J" spaces above the backbox panel: no effort is being made to move the

jackbox panel into a more operable location as recommended by Human

Factors.

The positioning of the operator turret in back of the G.E. 701

operator position in the A&C van was not recommended by Human Factors

Engineering. Because the turret is located in such a position, the

f command rack transistorized boards have limited access for maintenance.

1. Since the jackbox relocations would require field modification

change orders, the operators are satisfying their operational communi-

cation requirements by using other available jack outlets as substitutes.

5.4.10 Recommendations

The following recommendations are made by Human Factors

Engineering:

a. The present voice communication subsystem was designed anddeveloped prior to the compliance date of AF/SSD 62-44A"Human Engineering for the Air Force Satellite ControlSystem", dated 1 July 1962. As a result, only MIL-STD-803was used as a design guide. Therefore, functional and taskanalyses as well as a design assurance activity should beperformed.

b. When operational equipment is moved out of prime rack orconsole control areas, control panels or communicationequipment in outlying rack-console areas should be moved in-1to the vacant areas.

c. On-station hardware modification requests should be handledin an expeditious manner and released as soon as possible[for on-station implementation.

d. Request for communication modifications on-stations shouldcome directly through Human Factors Engineering so thatimmediate action can be taken or coordinated.

e. In order to alleviate the congested A&C van situation, theV operator turret and operator should be moved into thecommunication van, thus providing more working space for theconsole operators.

5-51

P HIL C 0W.3.tftN oK.gLoPME

WDL-TR2007

f. The operator turret should have a "lamp test" switch forchecking all of the 78 indicators and a volume control forthe handset. (The operator cannot hear well when the G.E.701 tape system is operating.)

g. If a Reeves type radar console is to be used for futureprograms, a location for a coumunication panel should bedesigned into the controlling area of the console.

h. Closer contact should be established between the communicationequipment manufacturer and Human Factors Engineering duringthe initial design and pre-production phases of the product.This will help to prevent the incorporation of any undesired,non-standard hardware in the ordered equipment and wouldresult in a product representative of the Human FactorsEngineering effort.
