This paper briefl y introduces the development of Mapping satellite-1 engineering construction and the mission of satellite system, detailed introduces the ability of satellite system and camera load; mainly expounds the key technologies and problems of photogrammetry about Mapping satellite-1 without ground control points. Including LMCCD camera, on-orbit calibration for camera parameters of space photogrammetry, adjustment for three-line array EFP images without ground control point, etc, reached and exceeded the engineering index requirement by the engineering practice; introduces the application situation of Mapping satellite-1, and puts forward development ideas about this satellite. It can gives basic reference for the Mapping satellite-1 engineering.
