Verification Operations
Voyager
1command operations consisted of the successful uplink of a Command Loss Timer
Reset on 1/8 [DOY 008]. The spacecraft
received the command.
There
were no Voyager 2 command operations during this period.
Sequence Generation Operations
Complete
sequence development of CCSL A070.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 58.9 hours of DSN scheduled support for Voyager 1 of which 26.1 hours were large aperture coverage. There were no real-time or schedule support changes made during the period.
There was one significant outage of
2.5 hours on 01/03 [DOY 003] due to rain at DSS-65 [DR M105188]
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 9. The EDR backlog
is 2 days.
Voyager
2 Data Processing and Operations:
There were 38.8 hours of
DSN scheduled support for Voyager 1 of which 6.3 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 day.
