Hi all,
I have looked at the orbit 0626 ATS file, IBEX_2023_299_o0626a_v001.scr and I approve.
The constraint violations in IBEX_2023_290_o0626a_v001.ccvr are from the removal of the ACT_SetSpinPulseProtectEnable Enable commands. The violations are acceptable.
The PL commands in IBEX_2023_299_o0626a_v001.scr match those in the STF, IBEX_2023_299_o0626a_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_2023_299_o0626a_v001.oef and as verified
with ibex_orbit.
There are no star tracker outages this orbit.
The ground station command sequences are correct and the timing and bit rates match those in the contacts file, IBEX_Orbit626_Contacts.txt for all contacts (3).
No Battery Balancing this orbit.
The Sun maneuver at perigee of orbit 0625 left us pointing in safe directions for the orbit 0626 arc A ascending and descending sequences:
