Voyager
Mission Operations Status Report # 2012-11-23, Week Ending November 23, 2012
Command Transmission & Verification Operations
Voyager 1 command operations consisted of the
uplink of a Command Loss Timer Reset on 11/21 [DOY 326/1615z]. The spacecraft received the command.
There were no command operations in support of Voyager 2 during the
period due to DSS-43 downtime.

Voyager 1 Data Processing and Operations:
There were 26.8 hours of
DSN scheduled support for Voyager 1 of which 26.8 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 17. The EDR backlog is 9 days.
Voyager 2 Data Processing and Operations:
There were 26.7 hours of DSN scheduled support for Voyager 2 of which 0
hours were large aperture coverage. Three schedule changes were made replacing
DSS-34 support for DSS-45 down due to a red Maser. First change on 11/17 [DOY 323] replaced 3.4
hours of DSS-45 with 3.3 hours of DSS-34 support. The second on 11/21 [DOY 326] replaced 4.0
hours of DSS-45 with 3.1 hours of DSS-34 support. The last change on 11/23 [DOY 328] replaced 4.0 hours of DSS-45 with 2.8 hours
of DSS-34 support The
total actual support was 24.5 hours of which 0 hours were large aperture
coverage. There were no significant
outages during the period
Science instrument performance was nominal for all
activities during this period. The EDR
backlog is 9 days.
Flight
System Performance
Voyager 1 performance was nominal during this
report period. Activities included LECP
Observations on 11/17 (DOY 322), 11/18 (DOY 323), 11/19 (DOY 324), and 11/20
(DOY 325).
Voyager 2 performance was nominal during this
report period.
