测绘卫星三线阵CCD相机定位误差分析

The Positioning Error Analysis of the Three-Line CCD Camera on Mapping Satellite

为提升测绘卫星三线阵CCD相机定位精度,介绍了成像原理和定位原理,讨论了影响定位精度的误差源。分析了各种误差源对定位精度的作用环节和作用程度,给出了现有或将来可行的提高定位精度的方法。目的不是针对某一个误差源提出一种具体的解决方案,而是为想要从事于卫星无控测绘领域研究工作的学者提供一个清晰的理论参考框架。

For improving the positioning accuracy of the three-line CCD camera on mapping satellite, the imaging and positioning principles were introduced and the error sources affecting the positioning accuracy were discussed in this paper. The affecting link and affecting intensity of each error source to the positioning accuracy were analyzed. Then, the current or the future methods of improving the positioning accuracy were proposed. The objective of this paper is not to provide a specific solution to one error source, but to provide a theoretical reference frame for the scholars who want to study in the field of satellite photogrammetry without ground control points.
