- MARS OBSERVER STATUS REPORT
- January 8, 1993
- 1:30 PM PST
-
- The spacecraft is in Array Normal Spin and continues to perform as
- expected. Teams are continuing to study the Attitude Control Subsystem
- miscompared star problem.
-
- Downlink is via the HGA (High Gain Antenna) at 2 kilobits per second.
- Uplink is at 125 bps using the LGA (Low Gain Antenna). HGA calibration
- activities were completed last evening. Those calibrations indicate
- HGA performance to be nominal.
-
- With completion of C5 B as scheduled at 7:00 PM last evening, no flight
- sequences are currently active. This is to provide a ten day window to
- allow upload of a new Flight Software build.
-
- Teams are preparing Flight Software Build 7.1.1 for uplink on January 13
- though 15. Build 7.1.1 contains changes to AACS (Attitude and Articulation
- Control Subsystem) Fault Protection logic determined to be necessary by
- the Spacecraft Team. These changes are not related to the Celestial
- Sensor Assembly miscompared star situation.
-
- The next Flight Sequence, C6 B (necessary C6 A activities were moved
- into C5 B) is scheduled to go active on January 18.
-
- Ka Band Link Experiment (KaBLE) activities have begun and are scheduled
- to take place daily through January 12. There are additional KaBLE
- opportunities projected for January 16 and 17.
