An attitude control system for satellites includes a sensor (10) for generating output signals in response to variations in the attitude of the satellite. These signals are applied to a Kalman filter (12) which models the dynamic state of the satellite and instructs an attitude controller (13) to generate control signals for controlling the actuators. The system is responsive to the actual physical performance of the actuators to provide feed back to the modelling circuit.
An attitude control system for a satellite, comprising: (a) thrusters for altering the attitude of the satellite; (b) a sensor for generating output signals in response to variations in the attitude of the satellite; (c) a Kalman filter for modeling the dynamic state of the satellite to which the sensor output signals are applied; (d) an attitude controller responsive to said Kalman filter for generating control signals for controlling said thrusters; and (e) pressure transducers associated with said thrusters so as to be responsive to the actual physica...
