Report # 2012-02-24, Week Ending February 24, 2012
Command Transmission &
Verification Operations
There were
no command operations in support of Voyager 1 during the period.
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 02/22 [DOY 053/1722z].
The spacecraft received three of the seven commands sent.
