电子经纬仪测量系统中立方镜坐标系建立技术探讨

A Technology to Get Coordinate-System of Cube-Prism in Electron-Theodolite Surveying System

在航天器总装过程中,通常利用立方镜来转移航天器分系统的位置关系基准,通过对基准立方镜之间位置关系的测量与调整,实现航天器的空间位置关系观测与调整。电子经纬仪测量系统在进行立方镜测量时,经常需要建立立方镜坐标系,本文介绍了电子经纬仪测量系统中构建立方镜法线的两种方法,对其优缺点进行了比较,并在此基础上,阐述了立方镜坐标系的构建方法。

In the process of assembling spacecraft, we usually transform position datum of spacecraft＇ s parts to its cube-prism, by measuring and adjusting cube-prism to make spacecraft＇ s parts in suitable position. When measuring cube-prism we often need to build up coordinate-system of cube-prism. Two methods to build up a normal of cube-prism is introduced. Under this foundation how to build up 3D coordinate-system of cube-prism in electron-theodolite surveying system is discussed.
