摘要
在卫星地面总装时,需要测量航天相机视轴之间以及相机视轴与其他敏感仪器或整星坐标系坐标轴之间的角度关系。文章以某线阵CCD相机的安装测量为例,介绍了使用经纬仪系统确定航天相机视轴的方法以及相机与相机之间、相机与整星坐标系坐标轴之间角度关系的测量。分析中对相机的光学系统进行了简化,重点介绍了测量方法的数学模型,并通过误差传递公式分析了测量精度,最后针对该测量方法的不足提出了改进措施。
In the process of satellite general assembly,the orientations of the axis of the cameras in the global coordinates of the satellite need to be measured.In this paper,the theodolite is used for that purpose.This paper describes how to define the axis of the camera and measure related angles.The theories and the precision of the technology are analyzed,the optical system of the camera is simplified,a mathematical model of measurement is built,and the precision is analyzed through transfer formulas.
