A study is reported on attitude measurement systems using outputs of optical and inertial sensors combined to provide a high quality attitude reference of spacecraft or inertial platforms, undergoing both small attitude precision motion (pointing mode), and large angle slewing motion. The systems considered use a star tracker capable of tracking two stars, and inertial quality rate integrating gyros. Processing is carried out digitally using a processor based on the Adaptive Control Electronics (ACE) computer. Two types of sensor mathematical models are discussed. Methods are evaluated of determining the satellite's attitude during a large angle slew maneuver.
