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.

 

Sequence Generation Operations

 

Continue sequence development of CCSL B163.

 

Data Return Operations

 

Voyager 1 Data Processing and Operations:

 

There were 47.0 hours of DSN scheduled support for Voyager 1 of which 42.3 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.  One frame of GS-4 data was recorded this week.  A second frame of GS-4 data was recorded on December 29.  The third frame of GS-4 data was recorded on January 2.  The EDR backlog is 3 days.

 

 

Voyager 2 Data Processing and Operations:

 

There were 36.7 hours of DSN scheduled support for Voyager 2 of which 25.7 hours were large aperture coverage. There were no real-time or schedule support changes made during the period.

 

There was one significant outage of 1.4 hours on 01/03 [DOY 003] due to a Red antenna at DSS-43 [DR C109758].

 

Science instrument performance was nominal for all activities during this period.  The EDR backlog is 3 days.

 

 

Flight System Performance

 

Voyager 1 performance was nominal during this report period.  Activities included DTR Maintenance on 12/31 (DOY 365) and a PMPCAL on 1/1/2014 (DOY 001).

 

Voyager 2 performance was nominal during this report period.
