The paper describes algorithms for on-board commanding, estimation and control of the attitude of maneuvering spacecraft using an on-board computer. Their performance is demonstrated in in-flight experiments with the Infra Red Astronomical Satellite. The following items are discussed: on-board commanding of the spacecraft attitude motion, a model following control technique for attitude maneuvering, an estimator for state feedback and disturbance torque compensation, a Kalman filter for inertial-optical attitude determination and estimation of gyro parameters.
