All,
I have looked at the Orbit 105 ATS v002
(IBEX_2010_345_00_00_v001.txt) and I .
The standard "PL mode unknown at the beginning" constraint
violation is the only one.
The PL commands match the STF v001 file
(IBEX_2010_345_18_02_v001.stf) per Ken's script. PL operations all
make sense WRT 15 Re times, ascending and descending.
Ground station times line up nicely with the transmitter on
times. The data dump is on a 35-minute pass; usually this pass is
longer.
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:
