Command Transmission & Verification
Operations
Voyager 1 command operations
consisted of the uplink of a command loss timer reset, CCSL A058
and CCS MRO on 01/10 [DOY 010/0507z]. The spacecraft received all commands
sent and the CCSL was verified.
There were no Voyager 2 command
operations during the period.
Sequence Generation Operations
Continue development of CCSL
B131.
Data Return Operations
Voyager 1 Data Processing and
Operations:
There were 100.1 hours of DSN scheduled support for Voyager 1 of which 36.7
hours were large aperture coverage. No real-time or schedule support changes
were made or significant outages occurred 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 day 007. The EDR backlog is 2 days.
Voyager 2 Data Processing and
Operations:
There were 61.8 hours of DSN scheduled support for Voyager 2 of which 29.3
hours were large aperture coverage. No real-time or schedule support changes
were made or significant outages occurred during the period.
Science instrument performance was nominal for all activities during this
period. One frame of GS-4 data was recorded this week. The EDR backlog
is 2 days.
Flight System Performance
Voyager 1 performance was nominal
during this report period.
Voyager 2 performance was nominal
during this report period. Activity included a PMPCAL on 1/10 (DOY 010).
