[Isocops] IBEX Orbit# 152 ATS v001 - approve

[Mark Tapley]

All,
	I have looked at the Orbit 152 ATS v001

IBEX_2012_007_o0152a_v001.txt

and I approve.

	Constraint violation per .ccvr file:

IBEX_2012_007_o0152a_v001.ccvr

	expected due to eclipse, battery balancing commands intended 
to address that.

	The PL commands in the ATS v001 match the STF v002

IBEX_2012_007_o0152a_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_2011_363_o0152a_v001.oef

	Moon in -Lo FOV PMT setback commands needed per the .oef, and 
match times approximately (.stf is concentric with .oef and inside by 
~1 hour).

	Ground station contact times and rates per

IBEX_2011_Orbit152_v002.caf

match S/C commands for first 2 contacts; last contact is after 
perigee maneuver and not in the command load.

	Battery cell balancing combined with eclipse operations this orbit.

	Inertial maneuver at the end of orbit 151 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

	-Lo O-mode Commands during both arcs.

	No overlaps to orbit 151 by manual check or by reference to 
http://ibex.unh.edu/cgi-bin/ats.cgi.

	No Command Approval Checklist - maybe later.

	No O-mode checklist - maybe later.

	-Hi Neg collimator voltage set to 1400V on arc A only.
