ACE Weekly 07/06/2007 - 07/12/2007 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: No maneuvers were completed this week. The next attitude maneuver is scheduled for Friday, 07/13/2007. ============================================================================ OCRs: DOY 190 (07/09/2007) GND-179 ROBOTT v1.0.3 Install String 1 This release of the ROBOTT ground automation software provides patches for transferring files on the Restricted IONet. ============================================================================ Activities: RIONET - ACE has fully transitioned to the Restricted IONet. JPL/DSN is no longer required to flow ACE data on the Closed IONet. Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the Library on April 28, 2006. Installation in the ACE MOC will not occur until after the MOC is converted to the RIONET. Planning continues for integrating ACE operations into a multi-mission ops center (MMOC). ============================================================================ Anomalies: DOY 189 07/08/2007 S-ACE-0206 G07-0062 ROBOTT Did Not Schedule Pass The ROBOTT ground software has difficulty processing a schedule with missing pass numbers. It also evaluates any DSN pass that has ' ACE ' in the activity field. This combination of problems is believed to have caused ROBOTT to skip the ACE pass on Sunday, DOY 189. The FOT reported to the MOC at 1515z (BOT+30 minutes) and started troubleshooting the ROBOTT problems. ROBOTT was restored at 1605z (BOT+80 minutes). IMPACT: SSR playback was completed on the following pass. If the DOY 189 pass was completely lost, an SSR failover would occur and it would take 3-4 passes to catch up on the playback. DOY 189 07/08/2007 S-ACE-0207 G07-0063 TPOCC/OS Bitbucket Error The HPUX operating system occasionally returns a bitbucket error when the TPOCC software executes a unix program. The ROBOTT automation software is designed to continue through the error. Usually this is not a problem, but on this occasion the procedure continued before the SSR redumps had been calculated. IMPACT: Due to the bitbucket error, we lost a 10 minute opportunity to catch up on the SSR playback. DOY 190 07/09/2007 S-ACE-0208 G07-0064 Prepass Activities Not Executed The ROBOTT ground software did not run the clock calibration or automated archiving. IMPACT: Minimal. Activities were performed manually.
