[Isocops] IBEX Orbit# 157 ATS v001 - approve

[Mark Tapley]

All,
	I have looked at the Orbit 157 ATS v001

IBEX_2012_053_o0157a_v001.txt

and I approve.

	No constraint violations per .ccvr file:

IBEX_2012_053_o0157a_v001.ccvr

	The PL commands in the ATS v001 match the STF v001

IBEX_2012_052_o0157a_v001.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_053_o0157a_v001.oef

	Moon in -Lo FOV occurs during star tracker outage on the 24th and 25th.
	Moon in -Lo FOV is reflected by .ATS commands; ATS lags 7.5 
and 5.5 hours behind (for a 25-hour Moon-in-FOV) .oef predictions, 
within normal tolerances.

	Ground station contact times and rates per

IBEX_Orbit157Contacts_v001.txt

match S/C commands for all 4 contacts.

	No battery cell balancing this orbit, did that last 2 orbits.

	Inertial maneuver at the end of orbit 156 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 safe 
direction at maneuver and at following Ascending and Descending 
Macros.

	No -Lo O-mode Commands.

	No overlap to orbit 156 apparent by manual check; 
http://ibex.unh.edu/cgi-bin/ats.cgi doesn't have Orbit 157 integrated 
yet.

	Command Approval Checklist attached.

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