Voyager Mission Operations Status
Report # 2012-06-29, Week Ending June 29, 2012
Command Transmission &
Verification Operations
Voyager
1 command operations consisted of the uplink of a Command Loss Timer Reset , CCSL
A084 and AHELIO SID MRO on 06/23 [DOY 175/0500z]. The spacecraft received all commands sent and
the CCSL and MRO were verified.
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 06/27 [DOY 179/1927z].
The spacecraft received three of the seven commands sent.
Sequence Generation Operations
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 54.1 hours of DSN scheduled support for
Voyager 1 of which 40.2 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. One frame
of GS-4 data was recorded this week. A
second frame of GS-4 data was recorded on June 29. The EDR backlog is 2 days.
Voyager
2 Data Processing and Operations:
There were 33.1 hours of DSN scheduled support for
Voyager 2 of which 12.6 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.
