Abstract: Satellite photogrammetry is a new means of obtaining geospatial information data, and it plays an important role in the global basic surveying and mapping. In this paper, the author reviewed the two stages of the development of satellite photogrammetry from personal experience in our country. Then, the theory of aerial triangulation adjustment for linear array push-broom image is mainly introduced. Finally, based on the engineering practice of TH-1 satellite, it is shown that through our independent theoretical innovation, the high location accuracy without ground control points (GCPs) can be achieved using single strip linear array stereo images, which can also reach the theoretical level of frame camera images.

Key words: photogrammetric satellite, aerial triangulation, camera parameters calibration, exterior orientation elements, location accuracy
