GENERAL DESIGN OF SPACE OPTICAL MAPPING REMOTE SENSING CAMERA

Abstract. Surveying and mapping plays an important role in all aspects of economic development, national infrastructure construction and national defence construction. Especially in the overall and strategic level, most of them need to apply geospatial information. Geospatial information acquired through surveying and mapping technology has become an important strategic resource. Because space photography is faster, cheaper and unrestricted by regions and borders, countries around the world are scrambling to develop their own mapping satellites. In recent years, great breakthrough has been made in the field of on-board optical stereo mapping, many countries have launched satellites with surveying and mapping as the main function, and obtained image data from 1:50000 to 1:10000 scale. This paper describes a design of a stereo surveying and mapping camera system that can achieve 1:10000 scale maps.
