[Isocops] IBEX Orbit# 149 ATS v001 - approve.

[Mark Tapley]

All,
	I have looked at the Orbit 149 ATS v001 and -Hi gain test ATS

IBEX_2011_345_o0149a_v001.txt
IBEX_2011_345_o0149a_HiGainTest_v001.txt

and I approve.

	No constraint violations per .ccvr files:

IBEX_2011_345_o0149a_v001.ccvr and IBEX_2011_345_o0149a_HiGainTest_v001.ccvr.

	The PL commands in the ATS v001 match the STF v002

IBEX_2011_344_o0149a_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_345_o0149a_v001.oef

	Moon in -Lo FOV PMT setback commands are concentric with 
period predicted in the .oef, and inside by 1 and 4 hours 
respectively, as usual.

	Ground station contact times and rates per

IBEX_Orbit149Contacts_v001.txt

match S/C commands for all 3 contacts.

	Battery cell balancing this orbit is more than an hour from anything.

	Sun-pointing maneuver at the end of orbit 148 left us 
pointing in a safe direction for ascending and descending macros 
during first half of orbit:

	No O-mode this orbit.

	No overlaps to orbit 148 by manual check or by reference to 
http://ibex.unh.edu/cgi-bin/ats.cgi.

	Command Approval Checklist attached.

	-Hi Neg collimator voltage set higher on first arc only.

	-Hi Gain test in separate ATS. Commands look OK.
