Sub Micro Radian Fine Tracking System Optimization Design

摘要：

The compound-axis APT servo control system is the important unit and key technology of the system of space laser communication, the fine tracking subsystem is further suppress the vibration residuals of the coarse tracking subsystem, it decides tracking accuracy of the whole servo system. This paper analyzes the impact of fine tracking error factor, and the characteristics of sources of error from the image detection and servo algorithm have been both optimized, We have built an experimental system in the laboratory and carried out experimental tests, In the simulation of satellite vibration condition can realize the tracking precision about 0.8 μ rad. The successful implementation of the sub-micro-radian dynamic tracking, Technological foundation for free space laser communication systems to achieve long-distance communications.
