Latest Patents
Ken Y Huang holds a patent for a "Satellite attitude determination and control system with agile beam." This invention features electronically steerable beam sensing with associated on-board processing. Originally used for positioning antennas for beam formation and tracking in communications systems, this technology is now also applied to satellite active attitude determination and control. The system utilizes a spinning satellite that is nadir oriented and precessed at orbit rate using magnetic torquing, determined through an on-board stored magnetic field model and attitude and orbit estimates. A Kalman filter is employed to predict parameters associated with a received signal impinging on the satellite's wide-angle beam antenna. The antenna system measures the error between predicted parameters and observed values, sending appropriate error signals to the Kalman filter for updating its estimation procedures. The Kalman filter also outputs spacecraft attitude error signals to an attitude control law, which determines commands to attitude-altering magnetic torque elements to close the control loop via the spacecraft dynamics.
