GS Readiness: FOT Training

All FOT have been on staff since before Payload I&T began.

All FOT had prior mission experience.

All FOT have rotated between R/T Analyst and Command Controller.

All FOT have worked as P/L Test Conductors.

All FOT have received Hands-On training from SI’s & CIDP as P/L TC’s

All FOT have received formal training from LMMS as well as OJT.

All FOT have participated in development of documentation.

All FOT have participated in development of the ODB.

FOT have been sole Payload Operators since 2/99

FOT have been operating S/C since Compat-Test 1 in 2/99.

FOT hours in command of Observatory approx. 50 days.

Payload and Observatory I&T systems are also used for Operations

Operations: Staffing

FOT has been at full staff (5) since 11/98.

FOT will downsize during transition to Automated Ops after IOC, to 2.5 Operators and will remain there until EOM.

Transition Planned for Launch + 60 days, only when Lights Out Concept has been validated.

GSM/MD (Burley) and MOM (Gustafson) are backup operators during IOC.

IOC will be staffed at 2 shifts per day, 12 hours per shift.– Note that during our spin-up periods we switch from ‘contiguous’ DSN coverage to a single pass

per orbit. This will provide some relief to FOT.

Operations: IOC Overview

First pass on DSS-66 at 22 minutes after separation. Re-Orient observatory spin axis on days 1 through 8. Open instrument doors to

facilitate out-gassing. Perform Spacecraft checkout, and LV SFF on several instruments. Power FUV/GEO. Switch from OMNI to Helix antennae when re-orientation complete.

Spin up to 13 RPM on days 8 through 16. Deploy RPI radial antenna to 120 m on day 16. Conduct MENA LV SFF and open

MENA shutters.

Spin up to 1.4 RPM on days 17 through 20.

Deploy RPI radial antenna to 160 m on day 20. Spin up to 0.96 RPM on days 21 through 24. Ramp EUV HV to Sun-Safe. Ramp FUV

to Science Level.

Deploy RPI radial antenna to 210 m on day 24.

Spin up to 0.75 on days 25 through 33. Open HENA Shutter.

Deploy RPI radial antennae to 250 m on day 35. Deploy RPI axial antennae.

Ramp-up high voltage on Science Instruments on days 36 through 39.

Begin Nominal Operations on day 40.

Operations: Nominal Ops

Automated Functions include:– Nominal Pass Execution.

– Observatory Health and Safety limit checking.

– Level Zero Processing.

– Execution of Science Data Processing scripts.

Manual Functions include:– Weekly Command Pass Execution, including receipt of weekly science stored commands

from PI and preparation of stored spacecraft commands.

– Weekly validation of onboard-derived attitude.

– Weekly system backups and Network Security Monitoring.

– Analysis of Trend Data.

– DVD Generation.

– Anomaly Resolution.

Operations: Contingency

32 Contingency Plans have been identified and documented. All have been tested with the Spacecraft or verified by analysis.

Observatory Health and Safety is monitored by ASIST, which alerts FOT via Skytel paging network via the SERS system.

SMOC provides L0 data and can flow real-time or recorded telemetry to remote instrumenters, LMMS Engineers & SwRI Engineers for troubleshooting.

All mission critical SMOC systems have backup hardware.

Mission Data is backed up in multiple locations (JPL, FEDS, DHDS, NSSDC).

FSW Maintenance:– SwRI provides FSW Maintenance of CIDP.

– LMMS provides FSW Maintenance of SCU s/w on a sustaining engineering contract to SwRI.

– SI’s provide FSW Maintenance for their instruments.

SOMO Readiness: Facilities

Critical IMAGE facilities at GSFC include the SMOC (B3 RmS25E/D) and data communications h/w in B3, B14 and B1.

All these facilities are physically secure with power backups.

Facilities Division has no activities planned which could interrupt service.

Work Freeze will be implemented around these facilities at L-6 hours.

SOMO Readiness: DSN

IMAGE is in DSN scheduling system, and is projected to receive all requested support.

Extensive compatibility tests between IMAGE and DSN/CTT have been successfully conducted on 8/98 (Transponder-only@JPL), and DTF-21 at JPL, 2/99, 5/99, 9/99 (Retest for Transponder fix), 12/99,1/11@WR.

Mission Readiness Tests have been run from all DSN sites during all shifts with data flows going to/from the IMAGE/SMOC at GSFC.

Operations agreement regarding communication between SMOC and JPL during lights out passes is nearing signature.

Implementation of 26m-subnet automation is now scheduled to occur during IMAGE IOC. DSN schedulers believe that this can be done with minimal to zero impact to IMAGE. IMAGE can/will remain on existing system.

Internal JPL/DSN Launch Readiness Review successfully held on January 31.
