PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2003-10-09 NOTE = "MGS RST Instrument Health Report HEA3282A.TXT" END_OBJECT = TEXT END Miscellaneous ============= Because the science value of ingress occultations obscured by the high- gain antenna (HGA) rewind is very limited, we have begun the practice of collecting only enough ingress measurements to monitor the effects of the rewind. As the HGA rewind moves back into the occulted time period (LMA predicts this will happen in early November) we will resume full collection of these data.

Ingress occultations are obscured by the HGA rewind, only one of which is reported here - the final DSS 43 observation (see Miscellaneous, above). Spurs are visible in power spectra of most occultations. They appear at the following frequencies relative to the carrier: DSS Frequencies (Hz) --- ------------------- 25 +/-180 26 +/-60, 180 43 +/-180 63 +/-50, 60, 180, 300 Uplink ramp leakage is present in the first three egress recordings at DSS 25 and DSS 26. The following occultations were captured at multiple antennas. Between DSS 25 and 26, the former appear to be better in the quick look analysis because of 1.5 dB higher SNR, fewer and weaker power-line spurs, and less noise around the carrier.
