Abstract: Global high-precision geolocation of satellite imagery without GCP is the main goal of satellite photogrammetry,and the fundamental supporting technology of mapping in abroad area.For the developing technology of domestic remote sensing satellite,this paper presents the high-precision geometric processing theory and method of high-resolution optical remote sensing satellite imagery without GCP.Based on rigorous analysis of satellite observation error model,on-orbit geometric calibration method,virtual re-imaging processing method and large-scale block adjustment method are proposed.Experiments were conducted by using ZY-3 imagery.The result fulfills the demand of 1:50 000 mapping,and proves the correctness of proposed theory and method.

Key words: high-resolution remote sensing imagery, high-precision geometric processing without GCP, on-orbit geometric calibration, virtual re-imaging, large-area block adjustment without GCP, ZY-3
