Report # 2009-06-12, Week Ending June 12, 2009
Command Transmission &
Verification Operations
There were no command operations in support of Voyager 1 during the period.
Voyager 2 command operations consisted of the uplink of Hpoint Update1, Mini Sequence to Read Out HPTBL and a Command Loss Timer Reset on 06/09 [DOY 160/1403z]. The spacecraft received all commands sent. The Hpoint update and Mini Sequence was verified.
Sequence Generation Operations
Continue
sequence development of CCSL A072.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 107.6 hours of DSN scheduled support for Voyager 1 of which 16.6 hours were large aperture coverage. There were no real-time or schedule support changes made or significant outages during the period.

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 June 12. The EDR backlog is
1 day.
Voyager
2 Data Processing and Operations:
There were 74.0 hours of DSN scheduled support for Voyager 2 of which 24.0 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.
