Abstract
A 2D model-based generalization of the gradient step-track is introduced and simulation results are presented showing an overall tracking accuracy improvement and limit signal-to-noise ratio (SNR) advantage over the hill-climbing and the gradient procedures. At best, the new method is shown to allow a worse than 20 dB SNR in tracking a near geosynchronous satellite.
