PDS_VERSION = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 1997-09-16 NOTE = "MGS RST Instrument Health Report HEA7259A.TXT" END_OBJECT = TEXT END Miscellaneous ============= ODS from the MOI occultations at DSS 14 continues to be unavailable on the NERT Cache. I phoned yesterday and was told that Data Control was working on restoring 97/255 at that very moment. SOE file t0305.01.soe (and the accompanying SFOS file) have been advertised in e-mail as superior to other SOE/SFOS combinations. They are available from http://mgsw3.jpl.nasa.gov/seq/seg homepage in PDF format. But they are not on the CDB 24 hrs after the e-mail was circulated. A pre-aerobraking occultation pair with the HGA was apparently missed yesterday when no one on the Radio Science Team knew that it was predicted. Data from 97/247-248, presumed lost yesterday to a tape malfunction, were recovered when Sun Service extracted the "daily" tape from the jammed 8 mm drive. The tape was readable and a new "cumulative" backup has been generated.

This simplified some of our processing since there was no reconstructed trajectory file for the ingress occultation (when the MOI burn was in progress). Anomalies --------- Still no DSS 14 data from MOI. Analyses -------- Processing the DSS 43 occultation data with SPK files in hand shows that both an ionosphere and neutral atmosphere were detected on the low- gain antenna. Joe Twicken has analyzed the last 9 minutes of the one-way egress data (after the spacecraft cleared the ionosphere). He reports Allan Deviations of 4.5221e-11 with 1.6384 sec points and 1.3353e-13 with 26.2144 sec points. He judges these "not" bad given the 27 dB SNR with the low-gain antenna.
