Hello team,
During the first perigee pass, the ebnos were extremely low so I switched the data rate to 160k and I was unable to get all the ssr
data blocks by the end of the contact. After the pass, SSC notified me of multiple vc2 sequence errors, so I reached out to Ken, and he advised to do a complete redump next perigee pass. I performed the following, dump SSR (VCid2), upload ATS for orbit 658
(CAR #1405) and reset master timer on string Ibex-2. The second perigee contact was nominal, and the inertial maneuver was successful.
Tasks Accomplished:
Reset Master Timer
Reset FDC Totals
Dump ssr data (vc2)
CAR #1405 Orbit 658 ATS upload
IBEX_2024_225_o0658a_v001 - 101 commands
