Space laser communication is widely used in military and civilian fields and has the very good application prospect and huge potential field because of wide frequency band, good directivity, high communication rate, good secrecy and low power consumption. The high tracking accuracy requirements are put forward for photoelectric system by Aviation and navigation field.The research significance of compound-axis servo system using a CCD detector of compound-axis servo system is introduced in space laser communication, and it analyzes the decoupling process and conditions of compound-axis servo system using a CCD detector in the process of tracking, and contrasts and analyzes the performance of the CCD detector and double detector servo control system, the experiment results show that CCD detector can meet tracking accuracy requirements. It mainly discusses that it uses prediction filter algorithm of high tracking accuracy to resolve the target lost in decoupling process because the FOV is changed, Kalman prediction theory and maneuvering target model under the maneuvering target are analyzed, at last, a modified maneuvering target model and adaptive filtering algorithm is presented, the method not only improves tracking accuracy but also resolves the target lost in decoupling process because the FOV is changed, and makes the tracking continuous and fast.
