An approach to on-board sampled data estimation and control of the attitude motion of maneuvering spacecraft is presented. Algorithms for model following control of attitude maneuvers; estimation of spacecraft state (attitude, angular velocity, disturbance, torque); and optical-inertial attitude determination, with estimation of gyro parameters (drift rate bias, scale factor error) were developed. The algorithms were validated in single-axis software simulations of an attitude control system of the type used in the Infrared Astronomical Satellite. The control system comprises a strapdown rate-integrating gyro and a slit-type star sensor for optical-inertial attitude sensing, a reaction wheel actuator, and a digital on-board computer. The truth models for simulation of the hardware components are discussed.
