基于公共点转换原理的综合精度检测方法研究

The Research of Joint Alignment Test Method Based on Switching Principle of Common Point

随着小卫星技术的快速发展,高分辨率光学遥感类小卫星及安装有特殊载荷的科学试验类小卫星对总装精度检测的要求不断提高。传统的经纬仪测量系统受测量原理所限,只能实现方位角测量;激光跟踪仪测量系统只能实现点位及形面测量。为了适应后续型号任务的综合精度检测需求,本文提供了一种基于公共点转换原理的综合精度检测方法。通过该方法,实现经纬仪测量系统与激光跟踪仪测量系统的坐标系转换和统一,完成点位坐标系和立方镜坐标系之间关系的检测任务。

With the rapid development of small satellites,the demand of assembly alignment is increasing for the highresolution optical remote sensing satellites and the scientific experiment satellites with special payloads. By the limit of measuring principle,traditional theodolite measuring system can only measure the azimuth angle,as well the laser tracker can only take the measurement of point and surface. In this paper,in order to fulfill the joint alignment demand of the future mission,a joint alignment test method is proposed,which is based on switching principle of common point. By this method,coordinate system switching and unity can be achieved for the theodolite measuring system and the laser tracker measuring system,and the test mission can also be achieved for the relationship between point coordination and cubic mirror coordination.
