Requirement of Apollo Telescope Mount (ATM) is accurate pointing of experiment package containing complement of solar experiments to acquire data on solar phenomen; vehicle with ATM will be placed in 485-km circular orbit to give experimenter atmosphere-free environment for solar observation; development of vehicle attitude control system, experiment-pointing system, and roll-positioning mechanism; first system uses three 2 degree-of-freedom control moment gyroscopes to supply control torques about three orthogonal vehicle axes; second system consists of two-axis gimbal trim system providing pitch and yaw positioning and control; roll-positioning mechanism can be driven and locked to any position over required roll offset range.
