Hi all,
I have looked at the orbit 0619 ATS file, IBEX_2023_237_o0619a_v001.scr and I approve.
The constraint violations in IBEX_2023_237_o0619a_v001.ccvr are from the removal of the ACT_SetSpinPulseProtectEnable Enable commands. The violations are acceptable.
The PL commands in IBEX_2023_237_o0619a_v001.scr match those in the STF, IBEX_2023_237_o0619a_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_237_o0619a_v001.oef and as verified
with ibex_orbit.
There is 1 star tracker outage this orbit. Outage begins at 2023-08-26 20:01:07 and lasts for 37.4 hours.
The ground station command sequences are correct and the timing and bit rates match those in the contacts file, IBEX_Orbit619_Contacts.txt for all contacts (2).
No Battery Balancing this orbit.
The Inertial maneuver at perigee of orbit 0618 left us pointing in safe directions for the orbit 0619 arc A ascending and descending sequences:
