This report summarizes data collection from the final three VEX solar conjunction observations made by the DSN. Other solar conjunction observations were summarized in HEA6297A.TXT and HEA6321A.TXT. Open Loop Data ============== Data Collection --------------- We have completed quick-look processing on the following VEX RSR open loop data at Stanford: DOY DSS RSR BAND RSR CH KSPS BT REC RECS RSR MAX START STOP ID RS LEN FILE NAME SNR --- --- -------- -------- ---- --- -- ---- -- ----- ----- ------------ ----- 325 15 20:29:01 00:19:00 X/XR 6 1 2 16 8260 13800 6325202A.RSR 56.0 325 15 20:29:01 00:19:00 X/SR 5 1 2 16 8260 13800 6325202B.RSR 18.0 327 43 20:39:00 00:15:00 X/XR 4 1 2 16 8260 12961 6327203A.RSR 56.6 327 43 20:39:00 00:15:00 X/SR 3 1 2 16 8260 12961 6327203B.RSR 25.8 327 43 20:39:00 00:15:00 X/XL 2 1 2 16 8260 12961 6327203C.RSR 39.6 327 43 20:39:00 00:15:00 X/SL 1 1 2 16 8260 12961 6327203D.RSR -2.7 339 43 21:23:01 01:13:00 X/XR 4 1 2 16 8260 13800 6339212A.RSR 59.7 339 43 21:23:01 01:13:00 X/SR 3 1 2 16 8260 13800 6339212B.RSR 27.1 339 43 21:23:01 01:13:00 X/XL 2 1 2 16 8260 13800 6339212C.RSR 40.5 339 43 21:23:01 01:13:00 X/SL 1 1 2 16 8260 13800 6339212D.RSR 4.5 These data appear to be of generally good quality. S-Band signal levels are unstable on day 325 until about 21:30. There may have been telemetry modulation on the downlink carrier for the first 40 minutes; dropouts are less easily explained. On day 339 there are many, short dropouts lasting perhaps one second on X-RCP. On X-LCP there appear to be pulses (increases in sample power on the order of 1 dB). Both of these phenomena lasted throughout the recording. The behavior is reminiscent of the anomalies seen in DSS 43 VEX bistatic radar and DSS 43 MGS radio occultation data starting in June 2006. There is no evidence of either dropouts or pulses in the data collected on day 327, also at DSS 43. Closed Loop Data ================ Data Collection --------------- We have collected, labeled, and stored the following closed-loop data on our system at Stanford. The files have also been copied to the jupiter system where they appear in directories /raid0/stanford/VEX/{ODF,TNF}. The following are ODF's at one-second sampling. Files with names of the form *A.ODF contain X-Band data; files with names of the form *B.ODF contain S-Band data.

The files have also been copied to the jupiter system where they appear in directories /raid0/stanford/VEX/{ION,TRO,WEA}. ION files are ionosphere media calibration files; these were calculated for Mars Express but should be equally good for VEX. TRO files are troposphere media calibration files. Each ION and TRO file covers (approximately) one month. ION and TRO files included here cover November and December 2006; the December files should have data for the first half of the month and predictions for the latter half. WEA files are meteorological data files (one for each DSN complex). Each file is cumulative for the year; these cover 01 January through 11 December 2006.
