Guys,
    Here is V002 of the Sun Precession Maneuver along with the ABS used in 
generation.
The STX off command for the Blind_Acq contact will be uploaded as a single 
command and has been omitted from V002
of the command load.
 The burn duration of the ABS has been extended to 1500.
 
Please review the attached ATS for comments/approval as soon as possible.
