All,
I have looked at the orbit 99 ATS
(IBEX_2010_299_00_00_v001.txt), and I approve.
The only constraint violation is the PL mode unknown
violation that we get every time.
Ken's script (thanks!) reports the PL commands are as in the
STF v002. PL operations all make sense WRT 15 Re times (given the
existing offset in ephemerides, yes I need to check that Real Soon
Now).
-Lo Star sensor set-backs match the moon-in-FOV times
reasonably well (sensor set-backs are over a narrower time but well
centered).
Transmitter on times line up with the ground station contact times.
No Battery cell balancing - are we done with that?
The sun-pointing maneuver leaves us in a safe direction at
the time of the maneuver and at the succeeding ascent and descent:
