Voyager Mission Operations Status Report # 2012-11-09, Week Ending November 9, 2012

 

Command Transmission & Verification Operations

 

Voyager 1 command operations consisted of the uplink of a Command Loss Timer Reset on 11/06 [DOY 311/1645z].  The spacecraft received the command.

 

Voyager 2 command operations consisted of the uplink of FDS DECK CHANGE and a Command Loss Timer Reset on 11/08 [DOY 313/0903z]. The spacecraft received all commands sent and the FDS DECK CHANGE was verified.

 

Sequence Generation Operations

 

 

Data Return Operations

 

Voyager 1 Data Processing and Operations:

 

There were 35.8 hours of DSN scheduled support for Voyager 1 of which 35.8 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 November 3.  The EDR backlog is 2 days.

 

 

Voyager 2 Data Processing and Operations:

 

There were 33.5 hours of DSN scheduled support for Voyager 2 of which 28.4 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.  Activities included a LECP Observations on 11/4 (DOY 310) and 11/6 (DOY 311) and a PMPCAL on 11/7 (DOY 312).

 

Voyager 2 performance was nominal during this report period.
