That report may not have been distributed earlier, so it has been sent again. Together HEA6297A.TXT and this report summarize most of the VEX solar conjunction data collection using the DSN. Three more passes are on the DSN schedule: day 325 at DSS 15, day 327 at DSS 43, and day 339 at DSS 43.

Previously scheduled solar conjunction data collection on days 305 and 312 did not happen; there was no VEX support in the DSN Keyword file at DSS 43 on either day. The reason for the schedule change is not known. DSS 43 VEX support on days 309 and 313 was lost so that the antenna could be used to deal with a Mars Global Surveyor spacecraft emergency. On day 298, there was no carrier on any channel between about 22:25 and 23:10. The reason for this gap is not known. The noise power seems to have been unaffected, so the ground antenna presumably continued tracking. On the pass which started on day 307, both carrier signals disappeared abruptly at about 00:05 even though end-of-track was scheduled to be 00:30. But the schedule was written for DSS 43, and there may have been a conflict at DSS 45 forcing early termination. This was the first day of the MGS spacecraft emergency. 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. The first file contains data from both S- and X-Band. The second file contains X-Band data, and the third contains S-Band data. It is likely that data in the first file have been repeated in the other two.

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 October 2006. WEA files are meteorological data files (one for each DSN complex). Each file is cumulative for the year; these cover 01 January through 13 November 2006.
