激光通信系统粗跟踪视轴标校方法

摘要

针对激光通信系统组成及技术特点,提出了一种粗跟踪视轴标校方法.该方法以双天线GPS/INS组合系统为零位基准,完成粗跟踪视轴与零位基准快速、高效对准.将此方法应用到飞机-飞机激光通信演示实验中完成粗跟踪视轴标校,校准精度4.7mrad.%According to the composition and technical characteristics of laser communication system,a simple and feasible line of sight calibration method on coarse tracking was put forward.The zero reference was provided by double antenna GPS/INS combined system,and fast,efficient alignment process was completed between coarse tracking line of sight and zero reference.This method was successful applied to laser communication demonstration experiment between aircrafts,and calibration precision is 4.7 micro-radians.
