Abstract
The GaoFen-3(GF-3) satellite is the first full-polarized synthetic aperture radar (SAR) imaging satellite of china, which was launched in August 2016. This paper obtained the geographic information based on the actual data from GF-3 satellite. Range-Doppler Model is used to process GF-3 data to verify the different between the position accuracy after correction and the practical positioning accuracy. The difference provides a certain reference for domestic satellites to promote actual positioning accuracy.
