Transmission-type stereo mapping micro-satellite payload and ground application system

Abstract

With the development of modern small satellite technology, it is potential and significant to use the new technology for the earth observation. The stereo mapping micro-satellite-"Experiment Satellite 1", designed and built by Harbin Institute of Technology, is taken as an example for discussion of the relevant technologies and corresponding principle of the satellite payload and its ground application system. The ground application system receives the stereo photographs data from the "Experiment Satellite 1" and then produces surveying products such as digital elevation map, digital orthoimage and digital topographic map, etc. "Experiment Satellite 1" is the first satellite where three-line-array CCD camera is used triumphantly in world for stereo mapping. It will have profound influence on the earth observation technique.
