Good morning team,

 

   The perigee contacts were nominal, and the inertial maneuver was successful. During the first perigee pass, we performed the following, dump SSR (VCid2), dump FC back orbit data (VCid1), upload ATS for orbit 653 and reset master timer on string Ibex-2. During the second perigee contact, we successfully loaded the Hi Normal sweep table and uploaded the ATS for orbit 654 on string Ibex-1.

 

 

Tasks Accomplished:

Reset Master Timer

Reset FDC Totals

Dump ssr data (vc2)

Dump FC back orbit data (vc1)
