All,
I have looked at the Orbit 104 ATS v002
(IBEX_2010_337_00_00_v002.txt) and I approve.
The standard "PL mode unknown at the beginning" constraint
violation is the only one.
The PL commands match the STF v001 file
(IBEX_2010_338_04_10_v001.stf) per Ken's script. PL operations all
make sense WRT 15 Re times, ascending and descending. The current
.oef is only off from the Orbit 102 Forecast .oef by ~2 minutes.
Ground station times line up nicely with the transmitter on times.
Battery cell balancing is > 1 hour from anything.
The sun-pointing maneuver leaves us in a safe direction at
the time of the maneuver and at succeeding ascent and descent:
