All,
	I have looked at the Orbit 100 ATS, and I approve.

	The only constraint violation is the standard PL mode unknown 
during perigee.

	PL commands appear (hand-checked) to match the v002 STF which 
Ken did (thanks Ken!) and look like a good match for the .oef in 
terms of when the Ascending and descending macros take place.

	No Moon-in-FOV periods.

	O-mode commands also look good.

	Transmitter on-times match the ground station contact times correctly.

	Battery cell balancing is an hour from everything.

	Sun-pointing maneuver leaves us in a safe direction at the 
time of the maneuver and at the succeeding ascent and descent:
