ACE Weekly 01/31/03 - 02/06/03 All ACE spacecraft subsystems are performing nominally. An attitude maneuver was successfully performed on 02/06/03. The next maneuver is scheduled for 02/14/03. ============================================================================ OCRs Executed: NONE ============================================================================ Ongoing Activities: TAPS: Trending, Analysis and Plotting System (TAPS) development continues. Testing is progressing on TAPS#2. TAPS#1 is still under control of the development team. ---------------------------------------------------------------------------- Automation (ROBOTT): The first release of Command & Control has also been pushed back to Feb 10. The first release of the Health and Safety Monitoring (HSM) has been delivered. ---------------------------------------------------------------------------- HGA Angle Constraint Report: Will be released soon. ============================================================================ Anomalies: DOY 03032 (02/01/2003) - ACE Anomaly Report #S03-0004 Mnemonic TANK_A2_T Yellow Low Limit Violation At 15:20:02, the mnemonic TANK_A2_T violated the yellow low limit of 10, with a value of 9.6472. At 15:20:10, the mnemonic TANK_A2_T returned to within limits. This has happened before. Reference AR S02-0024. The FOT is still investigating this. It does not look like a temperature fluctuation, but more like something with the temperature sensor. IMPACT: None at this time. DOY 03037 (02/06/2003) - ACE Anomaly Report #G03-0005 GDS(DSS-27) DSN - TGC Reboot / Late AOS At 14:48:00, DSS-27 informed the FOT that telemetry would be late (expected AOS 14:50:00). DSS-27 reported they loss interface to TGC-5. At 14:54:37, telemetry was put online. IMPACT: None. All telemetry was recovered. DR# G102303 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Glen A.
