All,

    The contact was nominal for TLM. The AGC was low throughout the pass (~-119 -> -122 DBm). Because of that I decided to hold off on sending up the Orbit 510 Instrument ATS. There was too much risk of dropping commands. We have 2 more uplink opportunities to send up the ATS. The 2 contacts are USHI01 12/06/20 341 05:30:00 - 06:30:00 64K & USHI01 12/06/20 341 08:00:00 & 09:00:00 160K. The Inertial maneuver was successful.
