中国无地面控制点摄影测量卫星追述（二）--1∶1万传输型摄影测量卫星技术思考

摘要

以1∶1万传输型摄影测量卫星工程有效载荷配置为基础，分析了传输型测绘卫星中影响定位精度的误差源，提出了激光测距数据辅助两线阵卫星影像处理的若干思路，并进行了模拟仿真试验。试验结果表明：利用激光测距数据参与两线阵影像光束法平差，能有效改善航线模型系统变形，并保持较小的上下视差，可满足卫星影像无地面控制点条件下1∶1万高精度定位要求。%In this paper, based on the payload configuration of high-resolution satellite engineering, the error source of positioning accuracy is analyzed in a data-transferring surveying and mapping satellite. Some ideas are put forward for two linear array satellite image processing with laser ranging data, and simulation experiment is carried out. The test results show that it can effectively improve the strip system deformation and maintain a small vertical parallax, and the high accuracy positioning without ground control points using satellite images can be met.
