Laser communication tracking system has important practical application value. In order to improve the performance of laser communication tracking system, a laser communication tracking system based on Kalman filter is proposed. Firstly, the working principle of the laser communication system is analyzed, and the research status of the laser communication tracking technology is expounded. Then, the moving nodes in the laser communication process are used as the tracking objects, and the tracking trajectories are tracked according to the Kalman filter. The experimental results show that, Kalman filter can effectively realize the position and velocity tracking of the node, and the tracking error can be controlled within the valid range, which can ensure the normal operation of the laser communication system.
