Abstract

Linear array CCD push-broom imaging system is adopted by CCD camera of HJ satellite as its imaging system. With the support of satellite ephemeris, attitude and the knowledge for CCD camera, a rigorous sensor model for CCD image of HJ satellite is constructed. Meanwhile, an error reduction model based on polynomial transformation using a few GCPs is used to compensate the positioning error. Experiments show that positioning error is about 185 pixels without GCPs, and it can be reduced to four pixels when three GCPs are used to compensate the positioning error.
