Voyager Mission Operations Status
Report # 2012-04-06, Week Ending April 6, 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 0.5 Hz steps on 04/02 [DOY 093/1732z].
The spacecraft received three of the seven commands sent.
Sequence Generation Operations
Start
sequence development of CCSL B156.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 38.7 hours of DSN scheduled support for
Voyager 1 of which 32.7 hours were large aperture coverage. There were no real-time or schedule support
changes made during the period.
There
was one significant outage of 2.1 hours on 04/04 [DOY 095] due to an antenna
halt at DSS-14, DR G112519.
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
April 6. The EDR backlog is 2 days.
Voyager
2 Data Processing and Operations:
There were 33.9 hours of DSN scheduled support for
Voyager 2 of which 8.2 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 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 4/3 (DOY 094).
