[Isocops] IBEX Orbit# 147 ATS v001 - approve.

[Mark Tapley]

All,
	I have looked at the Orbit 147 ATS v001

IBEX_2011_326_o0147a_v001.txt

and I approve.

	No constraint violations per IBEX_2011_326_o0147a_v001.ccvr.

	The PL commands in the ATS v002 match the STF v001

IBEX_2011_326_o0147a_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_326_o0147a_v001.oef

	No Moon in -Lo FOV PMT setback commands and none needed per the .oef.

	Ground station contact times per

IBEX_Orbit147Contacts_v001.txt

match S/C commands for all 3 contacts.

	No Battery cell balancing this orbit; we did last 2 orbits.

	Inertial maneuver at the end of orbit 146 left us pointing in 
a safe direction for ascending and descending macros during first 
half of orbit:

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

	No O-mode this orbit.

	No overlaps to orbit 146 by manual check; 
http://ibex.unh.edu/cgi-bin/ats.cgi seems to be running slow.

	No Command Approval Checklist today, maybe Monday.

	-Hi collimator voltage set higher at all ascending macro runs.
