IBEX_2016_166_o0330a_v001.scr,

and I approve.

The only constraint violations in

IBEX_2016_166_o0330a_v001.ccvr

are because we removed the

ACT_SetSpinPulseProtectEnable Enable

commands (2) and because of a long SSR dump contact; the violations are expected.

The PL commands in the v001 ATS match those in the v002 STF,

IBEX_2016_166_o0330a_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_2016_166_o0330a_v001.oef,

and as verified with ibex_orbit.

There are two star tracker outages.  The first starts about 2 1/2 days after apogee and runs for about 1 1/2 days.  The second starts about 4 1/2 hours before perigee and ends just before perigee.  Some despinning may be required due to the first outage.

There are no moon in Lo FOV sessions.

The ground station command sequences are correct and the timing and bit rates match those in the contacts file,

IBEX_Orbit330_Contacts.txt,

for all contacts (4).

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 329 left us pointing in safe directions for the orbit 330 arc A ascending and descending sequences:
