The LEO satellites rotate around the earth rapidly. Therefore auto-tracking techniques used in ground station, must have high accuracy for Telemetry, Tracking and Commanding (TT&C) and data acquisition-services. One of the most important of these techniques is conical, because of its low technical complexity and implementation costs and acceptable estimation accuracy, compared to monopulse technique. In this paper different aspects of the conical technique are analyzed. Also the best structure and required parameters of the conical technique for the LEO satellite tracking is proposed. Finally, by using of these parameters, root mean square error (RMSE) of conical tracking technique versus SNR is presented.
