Voyager Mission Operations Status
Report # 2009-01-16, Week Ending January16, 2009
Command Transmission &
Verification Operations
Voyager 1 command operations consisted of the uplink of a Command Loss Timer Reset and CCSL A070 on 01/16 [DOY 016/1230z]. The spacecraft received all commands sent and the CCSL was verified.
There were no command operations in support of Voyager 2 during the period due to the extended downtime of DSS-43.
Sequence Generation Operations
No
sequence development activities during this report period.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 59.9 hours of DSN scheduled support for Voyager 1 of which 36.8 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 January 16. The EDR backlog
is 2 days.
Voyager
2 Data Processing and Operations:
There were 31.7 hours of DSN scheduled support for Voyager 2 of which 0 hours were large aperture coverage. There were no real-time or schedule support changes made.
There was one significant outage of 2.4 hours on 01/11 [DOY 011] due to a timing failure at DSS-45 [DR C106755].
Science instrument performance was nominal for all
activities during this period. The EDR
backlog is 2 day.
Flight System Performance
Voyager
1 performance was nominal during this report period.
Voyager
2 performance was nominal during this report period. Activity included a PMPCSAL on 1/13 [DOY
014].
