Daily Report #5681
Period Covered:
07:00 pm February 1, 2012 - 06:59 pm February 2, 2012
(DOY 033/0000z - 033/2359z)
Significant Spacecraft Anomalies: (The following are preliminary reports of potential non-nominal performance that will be investigated.) HSTARs: none COMPLETED OPS REQUEST: 19204-1 - FGS AOI Patch Installation@33/1430z 19205-0 - TMDIAG and TLM Format Switch for AOI@33/1430z COMPLETED OPS NOTES: none FGS ACQ STATUS: SCHEDULED SUCCESSFUL FGS GSAcq 6 6 FGS REAcq 8 8 OBAD with Maneuver 4 3 SIGNIFICANT EVENTS: The installation of the FGS Attitude Observers Initialization patch took place today (2012/33). Ops Request 19204- FGS AOI Patch Installation and 19205 -TMDIAG and TLM Format Switch for AOI were followed to uplink Version D of the acquisition logic. The Acquisition logic was loaded and verified successfully. Overall the installation has proceeded nominally. An additional flash report will be issued late this afternoon after analysis of the first acquisition and reacquisition. The first guide star pair acquisition after the AOI patch installation occurred at 2012.033:16:49:11 and achieved Fine Lock nominally. Analysis showed that the AOI patch was operating as expected. The Reacquisition at 2012.033:18:25:33 also achieved Fine Lock. The Reacq occurred during a ZOE, but the vehicle was guiding in Fine Lock when telemetry was reacquired at 19:19:00. The first single star acquisition will occur at 2012.033:23:02:02. This acquisition will be monitored and a flash report will be sent out with its status afterwards. The first single star acquisition after the AOI FSW patch and Acq Logic installation occurred at 2012.033:23:02:02. The acquisition was successful and everything looked nominal during the acquisition process. Further monitoring of the acquisition statuses will be performed by the normal Acq Stats tool and reported by ARS.
