PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2002-01-30 NOTE = "MGS RST Instrument Health Report HEA2030A.TXT" END_OBJECT = TEXT END Errata ====== In HEA2024A.TST we reported low signal levels from one occultation: Data from occultation 12864i (DSS 65, start time 2002/023-10:50:00) have signal level about 15 dB below expectations. Cause is unknown. Engineers at SPC 60 report there was heavy rain during that period, the SNT rose to above 100K, and that telemetry data were lost. Miscellaneous ============= Aseel Anabtawi reports two changes in the scheduling of open-loop (radio occultation) measurements: Orbit 12958 later today is the last that is not configured for RS due to playback. 24 hr station coverage is also over with the DSS-25 pass today (EOT 9:10 p.m. PST). Therefore, we won't be losing measurements every third orbit for playback, but we'll be skipping measurements due to gaps in station coverage. We have submitted ISA Z73672 regarding delayed delivery of MGS ATDFs. Since mid-November we have received only one delivery of these files, and we have no data more recent than 2001/320. RMDCT appears to have a number of problems (staffing changes, hardware failures, mission critical activities), but we have also heard that they can't find some of the backlogged data. Hopefully, the ISA will prompt someone to look at RMDCT and try to give them some help (and us our data).
