VOYAGER MISSION OPERATIONS STATUS REPORT #1202, NOVEMBER 10 – NOVEMBER 16, 2001
COMMAND TRANSMISSION & VERIFICATION OPERATIONS
Voyager 1 command operations consisted of the uplink of a command loss timer reset on 11/14 DOY 318/1730z. The spacecraft received the command.
Voyager 2 command operations consisted of the uplink of seven bracketed command loss timer resets sent on five-minute centers using 0.5 Hz steps on 11/14 [DOY 318/2347z]. The spacecraft received four of the seven commands sent.
SEQUENCE GENERATION OPERATIONS
Start sequence development of CCSL A042.
DATA RETURN OPERATIONS
Voyager 1 Data Processing and Operations:
There were 63.0 hours of DSN scheduled support for Voyager 12 of which 32.1 hours were large aperture coverage. There were no real-time or schedule support changes during the period.
There was one significant outages of 7.4 hours duration on 11/11 [DOY 315] due to a red maser at DSS-63 [DR M100274].
Science instrument performance was nominal for all activities during this period. One frame of GS-4 data was recorded this week. Twenty-six frames of GS-4 data were played back from the spacecraft on November 10. Over 97% of the data were recovered. The AHELI1 cyclic for recording additional GS-4 data was enabled on November 12. The EDR backlog is 9 days.
Voyager 2 Data Processing and Operations:
There were 76.9 hours of DSN scheduled support for Voyager 2 of which 9.4 hours were large aperture coverage. There were no real-time or schedule support changes 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 10, using the BHELI 1 cyclic, which was enabled on July 14. The EDR backlog is 9 days.
FLIGHT SYSTEM PERFORMANCE
Voyager 1 performance was nominal during this report period. Activities included a DTR playback of PWS data followed by X-Band low power on 11/10 (DOY 314).
Voyager 2 performance was nominal during this report period. Activity included a PMPCAL on 11/13 (DOY 317).
