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 CCSL B154C
and a Command Loss Timer Reset on 01/06 [DOY 006/0649z]. The spacecraft
received all commands sent and the CCSL was verified.

There were 41.8 hours of DSN
scheduled support for Voyager 1 of which 35.0 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 6. The EDR backlog is 6 days.
Voyager
2 Data Processing and Operations:
