This paper briefly 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.
