空间光束实时捕获、跟踪实验与分析

Experimentation of Real-time Acquisition and Tracking of Dree Apace Laser Beam and Analysis of the Result

提出一种空间光束捕获、跟踪设计方案,在实验室条件下实现其主要功能,并对其定位精度和实时性进行了分析,结果表明信标光定位处理的时间为25ms,角度测量的相对误差为1.3%,显示出良好性能.同时,为由理论分析到实际星载PAT系统提供试验依据.

A project of acquisition and tracking of free space laser beam is advanced. And its major function is realized in laboratory. Analyses of precision of location and responsibility is given out. The results present positioning time of beacon is less than 25 ms and the relative error of position precision is less than 1.3%. This conclusion could be of some values for design of practical PAT subsystem on satellite.
