Voyager Mission Operations Status
Report # 2012-03-09, Week Ending March 9, 2012
Command Transmission &
Verification Operations
There were
no command operations in support of Voyager 1 during the period.
Voyager
2 command operations consisted of the uplink of seven bracketed Command Loss
Timer Resets sent on five-minute centers using 1.0 Hz steps on 03/05 [DOY 065/1727z].
The spacecraft received one of the seven commands sent.
Sequence Generation Operations
Start
sequence development of CCSL B155B.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 31.5 hours of DSN scheduled support for
Voyager 1 of which 19.8 hours were large aperture coverage. There were no real-time or schedule support
changes made or significant outages during the period.
Science instrument performance was nominal for all activities during this period. One frame of GS-4 data was recorded this week. A second frame of GS-4 data was recorded on March 9. The EDR backlog is 2 days.
Voyager
2 Data Processing and Operations:
There were 36.9 hours of DSN scheduled support for
Voyager 2 of which 21.8 hours were large aperture coverage. There were no real-time or schedule support
changes made during the period.
There was one significant outage of 2.3 hours on 03/03
[DOY 063] due to heavy rain at DSS-43, DR C108571
Science
instrument performance was nominal for all activities during this period. The EDR backlog is 2 days.
Flight System Performance
Voyager
1 performance was nominal during this report period.
Voyager
2 performance was nominal during this report period. Activity included a PMPCAL on 3/6 (DOY 066)
and a swap to the BC Gyros on 3/8 (DOY 068).
