Voyager Mission Operations Status
Report # 2012-01-13, Week Ending January 13, 2012
Command Transmission &
Verification Operations
Voyager
2 command operations consisted of the uplink of CCSL A082A and a Command Loss
Timer Reset on 01/09 [DOY 009/0515z]. The spacecraft received all commands sent
and the CCSL was verified.
Voyager
2 command operations consisted of the uplink of seven bracketed Command Loss
Timer Resets sent on five-minute centers using 1 Hz steps on 01/10 [DOY 010/2352z].
The spacecraft received one of the seven commands sent.
Sequence Generation Operations
Complete
sequence development of CCSL B155A.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 41.8 hours of DSN scheduled support for
Voyager 1 of which 33.3 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
January 13. The EDR backlog is 13 days.
Voyager
2 Data Processing and Operations:
There were 33.8 hours of DSN scheduled support for
Voyager 2 of which 28.3 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. The EDR backlog is 13 days.
Flight System Performance
Voyager
1 performance was nominal during this report period. Activity included turning ON the BC gyros on
1/12 (DOY 013).
Voyager
2 performance was nominal during this report period. Activities included X-Band high power, full
memory readouts, and X-Band low power on 1/8 (DOY 009) and a PMPCAL on 1/10
(DOY 010/011).
