[Isocops] IBEX Orbit# 145 ATS v001 - approve.

[Mark Tapley]

All,
	I have looked at the Orbit 145 ATS v001

IBEX_2011_308_o0145a_v001.txt

and I approve.

	No constraint violations per IBEX_2011_308_o0145a_v001.ccvr.

	The PL commands in the ATS v001 match the STF v002 file 
(including O-mode commands)

IBEX_2011_308_o0145a_v002.stf

per manual inspection.

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

IBEX_2011_308_o0145a_v001.oef

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

	Ground station contact times per

IBEX_Orbit145Contacts_v001.txt

match S/C commands for all 3 contacts.

	Battery cell balancing takes place more than an hour from anything.

	Inertial maneuver at the end of orbit 144 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.

	O-mode this orbit, from 2011/11:08:15:31:00 to 2011/11:12:21:58:00.

	No overlaps to orbit 144 by manual check or by viewing 
http://ibex.unh.edu/cgi-bin/ats.cgi.

	Command Approval Checklist and O-mode Checklist attached.

	Comet-viewing O-mode ends this orbit.
