SPACE VEHICLE HIGHLIGHT
All 7 Mass Trim Mechanisms (MTM's) were successfully tested on the GP-B spacecraft using both A and B sides of the Attitude Control Electronics (ACE). Each MTM was commanded to move for 3 minutes clockwise, and then 3 minutes counter-clockwise. Measurements verified the phasing and displacement after the MTM movements.
