Hi all,
I have looked at the orbit 0651 ATS file, IBEX_2024_162_o0651a_v001.scr and I approve.
The constraint violations in IBEX_2024_162_o0651a_v001.ccvr are from the removal of the ACT_SetSpinPulseProtectEnable Enable commands. The violations are acceptable.
The PL commands in IBEX_2024_162_o0651a_v001.scr match those in the STF, IBEX_2024_162_o0651a_v002.stf.
Ascending and descending command sequences are consistent with each other, 15 Re ascending, the apogee maneuver time and 15 Re descending as determined from
the OEF, IBEX_2024_162_o0651a_v001.oef and as verified with ibex_orbit.
There is 1 star tracker outage this orbit. Outage begins at 2024-06-19 18:40:49 and lasts for 11.3 hours.
The ground station command sequences are correct and the timing and bit rates match those in the contacts file, IBEX_Orbit651_Contacts.txt for all contacts
(4).
Battery Balancing is 90 minutes long, more than 2 hours away from payload descending macros, and more than 15 minutes away from a maneuver.
The Inertial maneuver at perigee of orbit 0650 left us pointing in safe directions for the orbit 0651 arc A ascending and descending sequences:
