[Isocops] IBEX Goat Herder for 25 Feb 2022

[Perry, Timothy E [US] (SP)]

All,
     The spacecraft is nominal. The inertial maneuver was successful. We had an issue on the USHI01 contact @07:00. They had an Antenna Control Unit issue and had to reboot it at AOS. Once the pass had started and we had started the SSR dump, we took another drop out in the downlink. We had a 10 minute data loss because of the dropout. Ken generated a CAR for the following contact and we were able to redump the complete orbit 558 data. The orbit 560 ATS was uplinked and the 18 day timer was reset to 10. SSC DR 15535 ACU Loss Of Connection was written on it.

Tasks Accomplished:
CAR #1228 Dump Orbit 558 blocks
CAR #1229 Upload ATS Orbit #560
SSR Dump -> Dump New
Reset 18 Day Timer
