The paper describes the Earth Acquisition Mode Extended Gyrocompass Controller flown aboard the NASA-CNES TOPEX/Poseidon Attitude Determination and Control Subsystem spacecraft for providing highly accurate measurements of the surface elevations over all the ocean basins. Particular attention is given to the on-orbit performance of the Extended Gyrocompass Controller used during quaternion initialization and Update Filter convergence processing, both of these procedures requiring maintenance of the spacecraft attitude control and knowledge. The development of the Extended Gyrocompass control technique is reviewed, and the results of the on-orbit yaw attitude control and knowledge performance provided by this algorithm are presented.
