Voyager
Command Transmission &
Verification Operations
Voyager 1 command operations consisted of the uplink of a Command Loss Timer Reset on 06/01 [DOY 152/1630z]. 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 06/02 [DOY 153/2042z]. The commands were not sent due to a procedural problem, ISA Z93816 was written.
Sequence Generation Operations
Continue
sequence development of CCSL A072.
Data Return Operations
Voyager
1 Data Processing and Operations:
There were 99.5 hours of DSN scheduled support for Voyager 1 of which 19.2 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
1.2 hours occurred over DSS-45on 06/04 [DOY 155, DR C106954]. The second outage of 0.5 hours occurred later
in the same day over DSS-65 [DR M105369].
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 June 5. The EDR backlog is 2
day.
Voyager
2 Data Processing and Operations:
There were 58.2 hours of DSN scheduled support for Voyager 2 of which 22.3 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. The EDR
backlog is 2 days.
Flight System Performance
Voyager
1 performance was nominal during this report period. Activity included DTR Maintenance on 6/2 [DOY
153].
Voyager
2 performance was nominal during this report period. Activities included a PMPCAL on 6/2 [DOY 153]
and turning on the AC gyros for conditioning on 6/4 [DOY
155].
