This has two main implications for Radio Science: (1) we will not be able to acquire egress measurements during beta-supplement mode, and (2) there will be approximately 16 minutes of tracking data outage during each orbit while the HGA rewinds. In order to obtain some egress measurements, there will be four to eight days per month of fixed-HGA operations. During these periods, the spacecraft will be NADIR pointed for 12 orbits (no downlink) followed by 4 orbits with the HGA fixed and Earth-pointed (no NADIR observations). The fixed-HGA mode is very similar to the previous fixed-HGA periods which occurred both before Mapping and right after the HGA AZ gimbal anomaly. The fixed-HGA periods for March are as follows (in UTC ERT): 066/03:35 to 066/11:35 067/11:35 to 067/19:35 068/19:35 to 069/03:35 075/11:30 to 075/19:30 076/19:30 to 077/03:30 077/03:30 to 078/11:30 I will keep you informed of future fixed-HGA periods. -Trish -------------------------------------------------------------------------- From ppriest@airmail.fltops.jpl.nasa.gov Sat Mar 18 00:59 PST 2000 Received: from thorn.fltops.jpl.nasa.gov (thorn.fltops.jpl.nasa.gov [137.228.90.10]) by magellan.stanford.edu (8.9.3/8.9.3) with SMTP id AAA01488;

If we don't use our predicts, then there is no way to know which DSP we are using. I don't usually check the attenuation levels from home. They had been very consistent about using DSP 1. I will start checking SPC 40 attenuation levels. -Trish Dick Simpson 723-3525 wrote: > >>There was an attenuation change in the baseline (DSS 45 084/03:28:00) >>because the attenuators were saturating.
