Voyager
Mission Operations Status Report # 2012-10-12, Week Ending October 12, 2012
Command Transmission & Verification Operations
Voyager 1 command operations consisted of the
uplink of a Command Loss Timer Reset on 10/09 [DOY 283/1855z]. 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 10/12 [DOY 286/1407z]. The spacecraft received three
of the seven commands sent.

Voyager 1 Data Processing and Operations:
There were 52.1 hours of DSN scheduled support
for Voyager 1 of which 52.1 hours were large aperture coverage. There were no
real-time or schedule support changes made during the period.
There was
one significant outage of 2.3 hours on 10/11 [DOY 285] due to a red antenna at
DSS-63 [DR M106947].
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 October 6. The EDR backlog
is 9 days.
Voyager 2 Data Processing and Operations:
There were 44.2 hours of
DSN scheduled support for Voyager 2 of which 13.4 hours were large aperture
coverage. There were no real-time or
schedule support changes made during the period.
There were two significant outages both due to
rain. The first outage of 2.1 hours
occurred over DSS-45 on 10/06 [DOY 280, DR C109017]. The second outage of 7.5 hours occurred also
during a DSS-45 support on 10/10 [DOY 285, DR C109025]
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. Activity included a
PMPCAL on 10/9 (DOY 283).
Voyager 2 performance was nominal during this
report period.
