Command Transmission & Verification Operations
Voyager 1 command operations consisted of the
uplink of a Command Loss Timer Reset on 11/14 [DOY 319/1625z]. The spacecraft received the command.
There were no command operations in support of Voyager 2 during the
period due to DSS-43 downtime.

Voyager 1 Data Processing and Operations:
There were 35.6 hours of
DSN scheduled support for Voyager 1 of which 35.6 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. One frame of GS-4 data was recorded this week. A second frame of GS-4 data was recorded on November 10. The EDR backlog is 2 days.
Voyager 2 Data Processing and Operations:
There were 36.4 hours of
DSN scheduled support for Voyager 2 of which 11.8 hours were large aperture
coverage. There were no real-time or
schedule support changes made during the period.
There was one significant
outage of 2.4 hours on 11/16 [DOY 321] due to rain at DSS-45 [DR C109116].
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. Activity included a LECP
Observation on 11/13 (DOY 318).
Voyager 2 performance was nominal during this
report period. Activity included a
PMPCAL on 11/13 (DOY 319).
