Report # 2009-03-06, Week Ending March 6, 2009
Command Transmission &
Verification Operations
There were no command operations in support of Voyager 1 during the period
There were no command operations in support of Voyager 2 during the period due to the extended downtime of DSS-43.
Sequence Generation Operations
Start
sequence development of CCSL A071.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 80.9 hours of DSN scheduled support for Voyager 1 of which 47.8 hours were large aperture coverage. One schedule change was made on 02/28 [DOY 059] when 1.8 hours of DSS-65 support was released to support MRO. The total actual support was 79.1 hours of which 47.8 hours were large aperture coverage.
There was one significant outage of 0.7 hours on 03/03 [DOY 062] due to rain at DSS-65 [DR M105258].
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 February 28. The EDR backlog is 2 days.
Voyager
2 Data Processing and Operations:
There were 49.0 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 1 days.
Flight System Performance
Voyager
1 performance was nominal during this report period. Activities included turning on the BC Gyros
on 3/3 [DOY 062] and a PMPCAL on March 4th [DOY 063].
Voyager
2 performance was nominal during this report period.
