[Isocops] IBEX Orbit# 159 ATS v001 - approve

[Mark Tapley]

All,
	I have looked at the Orbit 160 ATS v001

IBEX_2012_080_o0160a_v001.txt

and I approve.

	No constraint violations per .ccvr file:

IBEX_2012_080_o0160a_v001.ccvr

	The PL commands in the ATS v001 match the STF v001

IBEX_2012_080_o0160a_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_080_o0160a_v001.oef

	Star tracker outage from the 25th to the 27th. Moon in -Lo 
FOV commands are inside .oef predictions by up to 3 hours for a 3-day 
period; this is normal.

	Ground station contact times and rates per

IBEX_Orbit159Contacts_v001.txt

match S/C commands for the all 3 contacts.

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

	Inertial maneuver at the end of orbit 159 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 
direction at maneuver and at following Ascending and Descending 
Macros.
