Voyager
Mission Operations Status Report # 2012-11-09, Week Ending November 9, 2012
Command Transmission & Verification Operations
Voyager 1 command operations consisted of the
uplink of a Command Loss Timer Reset on 11/06 [DOY 311/1645z]. The spacecraft received the command.
Voyager 2 command operations consisted of the
uplink of FDS DECK CHANGE and a Command Loss Timer Reset on 11/08 [DOY 313/0903z].
The spacecraft received all commands sent and the FDS DECK CHANGE was verified.

Voyager 1 Data Processing and Operations:
There were 35.8 hours of
DSN scheduled support for Voyager 1 of which 35.8 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 November 3. The EDR backlog is 2 days.
Voyager 2 Data Processing and Operations:
There were 33.5 hours of
DSN scheduled support for Voyager 2 of which 28.4 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. Activities included a
LECP Observations on 11/4 (DOY 310) and 11/6 (DOY 311) and a PMPCAL on 11/7
(DOY 312).
Voyager 2 performance was nominal during this
report period.
