[Isocops] IBEX Orbit# 158 ATS v001 - approve

[Mark Tapley]

All,
	I have looked at the Orbit 158 ATS v001

IBEX_2012_062_o0158a_v001.txt

and I approve.

	No constraint violations per .ccvr file:

IBEX_2012_062_o0158a_v001.ccvr

	The PL commands in the ATS v001 match the STF v001

IBEX_2012_061_o0158a_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_o0158a_v001.oef

	Star tracker outage from the 4th through 9th, requiring 
sun-pointing maneuver at apogee.

	Ground station contact times and rates per

IBEX_Orbit158Contacts_v001.txt

match S/C commands for all 3 contacts.

	Battery cell balancing this orbit, skipped last time. 1.5 
hours, eclipse-flag FALSE is second command as appropriate.

	Inertial maneuver at the end of orbit 157 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

Macros.

	No -Lo O-mode Commands.

	No overlap to orbit 156 apparent by manual check or by 
reference to   http://ibex.unh.edu/cgi-bin/ats.cgi.

	Command Approval Checklist coming later.

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