ABSTRACT:
An antenna tracking controller for generating signals used to position an antenna for tracking a moving signal source includes a first Kalman filter for estimating parameters of a first model of the motion of the moving signal source a second Kalman filter for estimating parameters of a second model of the motion of the moving signal source. The second Kalman filter uses the parameters estimated by the first Kalman filter as initial values. A model quality charge/discharge is also provided to monitor the status of the data base.
