PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2000-05-15 NOTE = "MGS RST Instrument Health Report HEA0136A.TXT" END_OBJECT = TEXT END Miscellaneous ============= Because of the weekend, this is the first report since HEA0133A.TXT. The MGS bistatic radar experiment was conducted Sunday morning (03-11 AM JPL time) on orbits 5293-5295 with reception at DSS 63. Spacecraft performance appears to have been nominal, and good echoes were seen in real time from MPL latitudes on each orbit. Orbit 5294, which should have provided a swath directly across the MPL/DS2 landing area, also gave good echoes at latitudes 20-30S; these data may be useful for comparison against older results acquired using Earth-based monostatic radar systems. For reasons we don't fully understand, it was impossible to obtain reliable measures of system noise temperature (SNT) from the left-circularly polarized (LCP) channel. LCP is not a common configuration at the stations, but is sometimes used as backup and for radio science experiments (such as this). Absolute amplitude calibration of the LCP channel will therefore be difficult. But the RCP channel appears to be well characterized and may be adequate for most quantitative analyses. Data volume from each orbit is about 100 times that collected from a single MGS radio occultation, so the observations were recorded on tape for later shipment to JPL. We will attempt to transmit a short segment (5-10 minutes of the best MPL coverage) electronically tomorrow; a similar attempt this morning was unsuccessful because of configuration problems. The electronic transmission provides some protection against tape loss (copies have also been made) as well as improving delivery time by 2-4 weeks. Trish Priest and Sal Abbate were largely responsible for the successful radio science operation. At least two NOPEs provided support, and I understand half a dozen people from the Spacecraft Team were also on duty to monitor subsystems during this non-standard operation.

Occultations 5303i (DSS 65, start time 2000/136T08:29:00) and 5304i- 5305i (DSS 54, start times 2000/136T10:27:00 and 12:25:00) were lost when the DSP could not be switched from COPY mode. Levels in data from occultation 5306i (DSS 54, start time 2000/136T14:22:00) are about 8 dB low because of a faulty IF switch. A replacement switch has been sent to the station. Levels in data from occultation 5289i (DSS 34, start time 2000/135T05:02:00) are about 14 dB too low because attenuators were set for the wrong DSP. Noise level in data from the following occultations changes by about 1 dB about 90 seconds after ingress.
