Based on the actual research project, this paper describes a new shipborne satellite communication system based on conical scan and strap -down stabilization fiat and introduces its composition and principle. The system is characterized by completing antenna attitude stabilization tracking by the method of radar conical scanning and reducing the precision requirement of the antenna attitude stabilization. This paper mainly introduces the principle and composition of a new-type antenna automatic tracking system for mobile satellite communication, which is based on conical-scanning. It also analyses the impacts that different parameters have on the system and gives the choice principle. The experimental result shows time, and its antenna points to satellite quickly that the system has a high tracking precision and operates in real and stably, thus communication in moving is completed.
