[Isocops] IBEX Orbit# 187 ATS v002 - approve

[Mark Tapley]

All,
	I have looked at the Orbit 187 ATS v002

IBEX_2012_325_o0187a_v002.txt

	and I approve.

	One constraint violation per .ccvr file:

IBEX_2012_325_o0187a_v001.ccvr

	low battery state caused by long eclipse, as expected.

	The PL commands in the ATS v002 file match those in the STF

IBEX_2012_325_o0187a_v001.stf

	according to Ken's script (thanks!).

	PL ascending and descending operations make sense with 
respect to each other and to 15 Re ascending, Apogee, eclipse, and 15 
Re descending times from

IBEX_2012_325_o0187a_v001.oef

	Star tracker outage for 13 hours during first arc ascending 
and first 7 hours of science operations; should not affect ramp-up 
but may require de-spinning.
	Star tracker outage from 22nd through 26th requires 
sun-pointing maneuver at apogee.
	Star tracker outage from 28th through 29th requires 
sun-pointing maneuver at perigee.

	No Moon in -LO FOV.

	Ground station contact commands match contact times in Contacts file

IBEX_Orbit187Contacts_v001.txt

	for all 3 contacts. No contacts during eclipses. SSR dump 
contact on 29th overlaps cat-bed heater operation by 2 minutes, 3 
hours and 23 minutes after eclipse exit.

	Battery cell balancing unavoidable due to eclipse operations.

	Inertial maneuver at the end of orbit 186 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

	Sun-pointing maneuver at apogee leaves us pointing in a 
really safe direction at maneuver and at following Ascending and 
Descending Macros.

	No -Lo O-mode Commands.

	No overlap to orbit 186 commands apparent by manual check or 
by reference to http://ibex.unh.edu/cgi-bin/ats.cgi .

	Command Approval Checklist attached.

	-Hi Neg collimator back to operating at nominal voltage.
