航天产品对姿态参数提出高精度测量需求,立方镜-经纬仪准直测量法为其中应用最为广泛的方法。本文在对经纬仪自准直原理研究的基础上,针对产品姿态调整传统测量方法需多次架站、效率低的问题,提出事先计算调整理论值,将计算所得的理论值设置为观测参数,通过垫片对产品进行姿态调整,在一次架站的情况下,实现对产品姿态调整;同时,对该方法的适应范围进行讨论。经分析,该方法可实现对产品调整状态的实时测量,提高测量效率,减少操作强度,在实际应用中取得了良好效果。
Aerospace products pose high-precision measurement requirements for attitude parameters. The cube-theodolite collimation method is one of the most widely used methods. In this paper, based on the research of the theodolite self-collimation principle, aiming at the problem that the traditional measurement methods of the attitude adjustment need to stand a number of times and the efficiency is low, it is proposed to calculate and adjust the theoretical value in advance, set the calculated theoretical value as the observation parameter, Gasket to adjust the attitude of the product, in the case of a station, to achieve product posture adjustment; the same time, the scope of the method to be discussed. After analysis, this method can realize the real-time measurement of product adjustment status, improve the measurement efficiency and reduce the operation intensity, and achieved good results in practical application.
