The performance of the Space Shuttle based Starlab experiment intended to provide an on-orbit demonstration of acquisition, tracking, and pointing dynamics is analyzed. Simulation and test methods used to generate on-orbit performance estimates are presented. The Starlab Pointing Control System is based on an advanced flight computer which intermeshes analog control loops of its mirror controlling servos. Solid state multiplying digital analog converters are used to introduce digitally derived transformation relationships to the analog channels. An end-to-end scientific simulation of the system hardware and software uses mathematical models of optical tracking, including space object imagery and the beam control mirror servos. A special test set has been developed to provide a special purpose hardware system supported by an external computer for supplying an emulated interface of the Starlab actuators, sensors, and effective geometric line of sight conditions.
