摘要	High tracking accuracy is a prerequisite of reliable space optical communication links and its effective means is the utilization of coarse and fine compound-axis structure. After an in-depth study of the active laser tracking mechanism of fine tracking assembly, this paper emphasizes the exploration of these methods enabling the improvement of tracking accuracy under the condition of relative movement and platform vibration. Firstly, switching technique using a single beacon between different divergence angles is put forward to improve the signal to noise ratio (SNR) of the focal spot. Secondly, the high-frame rate charge-coupled device is achieved after proposing the pseudo random window readout technique. Thirdly, the unique design of the high resonant frequency of two-dimensional PZT fast steering mirror (FSM) and sub-pixel subdivision technique with adaptive control of integral time is used to achieve high accuracy and fast beam pointing. Fourthly, this paper puts forward a digital servol control method with intelligent variable structure. Finally, after building a hardware-in-loop simulation platform, the tracking accuracy of 3rad is concluded according to simulation experimental results.
