[Isocops] IBEX Orbit# 176 ATS v001 - approve

[Mark Tapley]

All,
	I have looked at the Orbit 176 ATS v001 (No -Lo commands)

IBEX_2012_225_o0176a_v001.txt

and I approve.

	No constraint violations per .ccvr file:

IBEX_2012_225_o0176a_v001.ccvr

	The PL commands in the ATS v001 match the STF v002

IBEX_2012_225_o0176a_v002.stf

per Ken's script (thanks!).

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

IBEX_2012_225_o0176a_v001.oef

	Star tracker outage near perigee after completion of inertial maneuver.

	No Moon in -LO FOV setback and none needed.

	Ground station contact times in command load match ground times in

IBEX_Orbit176Contacts_v001.txt

	for all 3 contacts.

	No Battery cell balancing this orbit, did that last orbit.

	Inertial maneuver at the end of orbit 175 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

Macros.

	No -Lo O-mode (or any) Commands. Star sensor commands coming 
in a later load?

	No overlap to orbit 175 commands apparent by manual check or 
by reference to http://ibex.unh.edu/cgi-bin/ats.cgi .

	Command Approval Checklist attached.

	-Hi Neg collimator voltage back to operating at nominal voltage.
