Command Transmission & Verification Operations

Voyager 1 command operations consisted of the uplink of a command loss timer reset, CCSL A058 and CCS MRO on 01/10 [DOY 010/0507z].  The spacecraft received all commands sent and the CCSL was verified.

There were no Voyager 2 command operations during the period.

Sequence Generation Operations

Continue development of CCSL B131.

Data Return Operations

Voyager 1 Data Processing and Operations:

There were 100.1 hours of DSN scheduled support for Voyager 1 of which 36.7 hours were large aperture coverage. No real-time or schedule support changes were made or significant outages occurred 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 day 007.  The EDR backlog is 2 days.

Voyager 2 Data Processing and Operations:

There were 61.8 hours of DSN scheduled support for Voyager 2 of which 29.3 hours were large aperture coverage. No real-time or schedule support changes were made or significant outages occurred during the period.

Science instrument performance was nominal for all activities during this period.  One frame of GS-4 data was recorded this week.  The EDR backlog is 2 days.

Flight System Performance

Voyager 1 performance was nominal during this report period.

Voyager 2 performance was nominal during this report period.  Activity included a PMPCAL on 1/10 (DOY 010).
