Voyager 1 Data Processing and Operations:
There were 28.6 hours of
DSN scheduled support for Voyager 1 of which 28.6 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 October 27. The EDR backlog is 1 days.
Voyager 2 Data Processing and Operations:
There were 33.4 hours of
DSN scheduled support for Voyager 2 of which 30.3 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 days.
