Voyager 1 Data Processing and Operations:
There were 29.5 hours of
DSN scheduled support for Voyager 1 of which 21.5 hours were large aperture
coverage. There were no real-time or
schedule support changes made during the period.
There was one significant outage of 3.6 hours on 11/29 [DOY 334] due to rain over DSS-24/25 array and red Maser at DSS24 [DRs G113441, G113442 and G113443].
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 November 24. 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 or significant outages during the period.
Science instrument performance was nominal for all activities during this period. The EDR backlog is 2 days.
