Abstract
Systems and methods of controlling and correcting the attitude of a spacecraft or a spacecraft-based payload due to disturbances that cause attitude changes determined by a spacecraft attitude measurement sensor and one or more additional attitude measurement sensors on the spacecraft. The systems and methods measure the attitude of the spacecraft and measure relative attitude errors between the spacecraft and the payload. The measurements are processed to generate control signals that selectively control the pointing direction of the spacecraft or payload. Embodiments are disclosed wherein the additional attitude measurement sensor is disposed on a platform that is stable with respect to the spacecraft attitude measurement sensor, and wherein it is disposed on a platform that is not stable with respect to the spacecraft attitude measurement sensor. Another embodiment is disclosed having a plurality of spacecraft attitude measurement sensors, one each for the payload and for the spacecraft attitude measurement sensor.
