In order to achieve the communication between the ship board antenna and the synchronouscommunicationsatellite, a method by the digital guiding closed loop and level open loop tracker is presented.
It is proved that this system automatically steers the direction of a receiver antenna and locks a synchronoussatellite in order to acquire best communication signal.
经实践验证，该系统实现了自动控制接收天线转向并锁定某一个同步通信卫星，以获得最佳的通信信号。
