IBEX_2017_118_o0365a_v001.scr,
and I approve.
The only constraint violations in
IBEX_2017_118_o0365a_v001.ccvr
are from the removal of the
ACT_SetSpinPulseProtectEnable Enable
commands (2); the violations are expected.
The PL commands in the v001 ATS match those in the v002 STF,
IBEX_2017_118_o0365a_v002.stf.
Ascending and descending command sequences are consistent with each other and 15 Re ascending, the apogee maneuver time and 15 Re descending as determined from the OEF,
IBEX_2017_118_o0365a_v001.oef,
and as verified with ibex_orbit.
There are no star tracker outages.
There is one moon in Lo FOV session in arc B. The ATS start time is about 1 1/2 hours after that in the OEF and the ATS end time is about 4 hours before that in the OEF. These differences are not unusual.
The ground station command sequences are correct and the timing and bit rates match those in the contacts file,
IBEX_Orbit365_Contacts.txt,
for all contacts (3).
We are doing battery cell balancing this orbit and the balancing commands are correct and offset by enough time from other commands.
The inertial maneuver at perigee of orbit 364 left us pointing in safe directions for the orbit 365 arc A ascending and descending sequences:
