Hello team,

 

   The perigee contacts were nominal, and the inertial maneuver was successful. During the first perigee pass, we performed the following, dump SSR (VCid2), upload ATS for orbit 656 and reset master timer on string Ibex-2. During the second perigee contact, we successfully ran the set spacecraft time script on Ibex-2. The signal was not strong enough and our agc was not stable, so we decided not to switch over to Ibex-1 to test the script.

 

Tasks Accomplished:

Reset Master Timer

Reset FDC Totals

Dump ssr data (vc2)

CAR #1401 Orbit 656 ATS upload
