Abstract

Dynamic and high tracking accuracy is the prerequisite of reliable space laser communication links and its effective means is using of coarse and fine compound-axis structure. This paper analyses these specific factors that effect the bandwidth and tracking accuracy of Fine Tracking Assembly (FTA), and puts forward corresponding methods with respect to optimization of techniques and selection of devices. After building hardware-in-loop simulation platform, the tracking accuracy of 3 urad is concluded according to experimental results, which verifies the effectiveness of these methods.
