摘　　要：为实现快速定位定向的要求,利用线阵CCD测量方法,设计了二维基准传递系统,实现北斗定向信息实时传递功能。该系统由北斗定向天线、光源模块和光学测量模块等组成,采用N型目标光源和线阵CCD拼接技术,实现二维基准信息的快速精确传递。利用构建的二维基准传递系统设计精度验证实验,实验结果表明,在测量距离8 m条件下,该系统测角范围为±1.5°,测量精度在5″以内。该方法为实现二维定向基准的大视场传递提供了一种有效的技术解决措施。To realize locating and heading determination fast,a two-dimensional referrence transfer system was proposed which can achieve real-time transferring of heading determination information for Beidou satellite navigation system（BDS）by linear charge coupled device（CCD）.This system consists of the BDS heading determination aerials,the light source part,the optical measuring part and so on.It can realize 2D measurement rapidly and accurately by using the N shape light source and linear CCD splicing technology.A precision testing experiment was designed based on the 2Dreference transfer system.The test results shows that on the condition of 8m measuring distance,the measuring range is±1.5°,and the measuring accuracy is no more than 5″.This system provides an effective technical solution for 2D determination heading reference wide-field transferring.
