摘　　要：以星载天线指向机构为研究对象,分析了以往测量方法的不足,提出了一种非接触式测量方法,解决了传统测量方法中部分机构指向精度和速度稳定度测量困难的问题,为星载机构精度测量添加了一种新的测量手段,同时以某一星载天线指向机构为例进行了实测和数据分析,结果表明该方法简单有效。In this paper, several present methods on velocity accuracy measurement of antenna pointing had analyzed and a noncontact measure ment method had proposed. This method as a new measurement way can be used to settle the difficul ties on the pointing accuracy and velocity stability measurement for particular mechanism. Using this method, the measurement test and data analysis bad performed for an antenna pointing mechanism and the results shows the proposed method is simple and effective.
