Abstract: | step tracking is currently considered as the most cost - efficient system at 6/4GHz satellite ground station. This paper described conventional step- track method and analysis its shortcoming. In order to enhance tracking quality, a new method which is based on gradient estimation has been proposed. By simulation, gradient step method is proved to be superior to old ways. |
