All,
I have looked at the Orbit 163 ATS v001
IBEX_2012_107_o0163a_v001.txt
and I approve.
One soft constraint violation per .ccvr file:
IBEX_2012_107_o0163a_v001.ccvr
Ryan's plot of battery level shows this is acceptable.
The PL commands in the ATS v001 match the STF v001
IBEX_2012_106_o0163a_v001.stf
per Ken's script.
PL ascending and descending operations make sense with
respect to 15 Re ascending, Apogee, and 15 Re descending times from
IBEX_2012_107_o0163a_v001.oef
Star tracker outage from the 23rd to 24th does not affect maneuvers.
Ground station contact times and rates per
IBEX_Orbit163Contacts_v001.txt
match S/C commands for all 3 contacts.
No battery cell balancing this orbit; we did last two orbits.
Inertial maneuver at the end of orbit 162 left us pointing in
a safe direction for ascending and descending macros during first
half of orbit:
