Report # 2012-07-06, Week Ending July 6, 2012
Command Transmission &
Verification Operations
Voyager
1 command operations consisted of the uplink of a Command Loss Timer Reset on 07/06
[DOY 188/2200z]. The spacecraft received
the command.
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 07/02 [DOY 184/1927z].
The spacecraft received three of the seven commands sent.
Sequence Generation Operations
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 55.0 hours of DSN scheduled support for
Voyager 1 of which 44.2 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 July 6. The EDR backlog is 2 days.
Voyager
2 Data Processing and Operations:
