Voyager 1 Data Processing and Operations:
There were 60.8 hours of
DSN scheduled support for Voyager 1 of which 58.1 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 September 7. The EDR backlog is 2 days.
Voyager 2 Data Processing and Operations:
There were 40.8 hours of
DSN scheduled support for Voyager 2 of which 28.7 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.
