Zusammenfassung:In this paper a new method for satellite authomatic tracking presented by earth station via doppler frequency . This method done by calculating time diviation through difference between real dopper frequency  by communication equipment and software Doppler frequency by theoretical TLE via STK Software. Then Kepler parameters are chaned so this deviation limit to zero. By this action correct antenna direction to satellite and receiving signal without error. Method test was done by amature satellite in UHF frequency band & CW Modulaition.Â
