Report # 2009-03-13, Week Ending March 13, 2009
Command Transmission &
Verification Operations
Voyager 1 command operations consisted of the uplink of a Command Loss Timer Reset on 03/09 [DOY 068/1430z]. The spacecraft received the command.
There were no command operations in
support of Voyager 2 during the period due to the extended downtime of DSS-43
Sequence Generation Operations
Continue
sequence development of CCSL A071.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 77.4 hours of DSN scheduled
support for Voyager 1 of which 42.2 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 March 7. The EDR backlog is
2 days.
Voyager
2 Data Processing and Operations:
There were 45.3 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 or significant outages during the period.
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. Activities included a MAGROL followed by
gyros OFF on 3/11 [DOY 070].
