anomaly report #G99-0018 and DR #N50404).
(2) At ~17:00 MOC noted that Ground FSN had incremented by 1.

Pass Summary:
- R/T ops exectued from G.A.S facility
- Experienced numerous Frame Sequence errors due to Frame received
with invalid S/C id. The frequency of these errors were more than what is
nominally experienced during support. Troubleshooting of problem with
DSN/JPL and IPNOC were inconclusive.
- The frame sequence errors were also occuring on MOR string.
- Redumped SSR for numerous missing frames from some slices.
After redumps completed , VC4 frames continued to be updated on G.A.S
Standard Header page although the SSR was in idle mode. This was not
occuring in MOR and VC4 updates had stopped in MOR
- Recycled G.A.S Mission S/W to investigate if VC4 frame updates
would continue. VC4 frame updates continued after Recycle of S/W
Anomalies
G99-0023 - Frame Sequence errors with Bad S/C ID
G99-0024 - VC4 Frame updates in Rel 5.0 when SSR in IDLE mode

recoverable. Performed weekly SWEPAM calibrations successfully.
Anomalies:DR G04690 generated on station receiver #1. Prior to BOT
the station reported a bad tlm channel#1 (unable to lock). Station
switched to channel #2, data improved but still had dropouts (see AR#
G99-0025). During the pass the station was queried as to the status of
channel #1, (sta reported 'no change from previous report'). At 17:40
initiated a failover from channel 2's tlm path to channel 1's tlm path and
channel two's tlm receiver - data quality improved.
