Voyager Mission Operations Status Report # 2006-02-24, Week Ending February 24, 2006

Command Transmission & Verification Operations

Voyager 1 command operations consisted of the uplink of a command loss timer reset on 02/24 [DOY 055/1600z]. The spacecraft received the command.

Voyager 2 command operations consisted of the uplink of a CLT MINI-Sequence on 02/23 [DOY 0054/2342z]. The spacecraft received the commands and the sequence was verified.

Sequence Generation Operations

Continue development of the new CCSL B131.

Data Return Operations

Voyager 1 Data Processing and Operations:

There were 98.9 hours of DSN scheduled support for Voyager 1 of which 56.8 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 49. The EDR backlog is 2 days.

Voyager 2 Data Processing and Operations:

There were 62.2 hours of DSN scheduled support for Voyager 2 of which 56.9 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.
