[Isocops] IBEX Goat Herder for 25 Nov 2022

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

All,
   The first 2 contacts were nominal. The Inertial maneuver was successful. I was able to dump the SSR 2 times, once prior to the eclipse and then a small dump post eclipse. The spacecraft was nominal post eclipse. The battery was full charged and over all the spacecraft looked nominal. The spacecraft clock was set and verified during the second contact. The Orbit 589 Lo gain Curve ATS and the Orbit 588 Australia ATS was uplinked during the first contact.
    The USAK01 contact was failed again. This time we were able to see telemetry, but they were unable to initialize the command carrier. After 20 minutes into the contact I was notified that they would not be able to initialize the command carrier. They would have to contact site personnel and have them look into why the transmitter was not working.

SSR Dump – Dump New 2x
