ACE Weekly 10/13/06 - 10/19/06 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: Type Attitude Date 10/19/2006 DOY 292 2006 Thrusters 2R 4R- 4R+ Duration 11:12 min Start 16:16:32z Stop 16:27:44z StartHGA -5.38 deg StopHGA 6.29 deg Firing 57 pulses FinalSCMass 1394.833lbs The next attitude maneuver is scheduled for 11/02/2006. ============================================================================ OCRs: None ============================================================================ Ongoing Activities: Attitude Training - The OE's have begun training the remainder of the FOT on attitude determination. Clock Calibration - TPOCC v5.3 engineering release was compiled on String 3 on 10/19/2006. A checkout is being performed in preparation of the official delivery. Three DRs to be fixed in this release. DR 22309 - Extend the number of years in the Clock Calibration file. DR 22411 - Clock Calibration Numerical Error DR 22446 - Increase precision of offset in clock report. RIONET - The transition to the RIONET on String 3 will occur after the next ROBOTT delivery. Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the Library on April 28, 2006. The delivery to the ACE MOC will not occur until after the MOC is converted to the RIONET. Automation - The ROBOTT SPS release test summary report has been finalized. The next full ROBOTT release is not expected until after the TPOCC/Clock Calibration release. ============================================================================ Extra Activities: DOY 287 (10/14/2006) - No pass was available. The impacts are * SSR failover on DOY 288 10/15/2006. * 31 seconds of data loss during the SSR failover. * No clock calibration report for DOY 287 and DOY 288 * No attitude orbit report for DOY 287. ============================================================================ Anomalies: DOY 289 (10/16/2006) S-ACE-0015 (G06-0095) - ACETLANPC not responding ACETLANPC was stopped working on Sunday DOY 288. SysAdmins rebooted the pc and it appears to be functioning nominally. IMPACT: Minimal. No DSN Monitor data was saved for DOY 288. DOY 288 archive files were transferred on Monday before weekly archive activities were performed. PC continues to be monitored.
