Satellite Image Positioning Method Based upon Aligning Surface Characteristics

The satellite data positioning is to calculate the longitude and latitude of instant scanning surface from satellite, traditional location methods is done by the satellite location at the observation time, satellite attitude and scanning angle. But satellite position and attitude often can´t be obtained or the precision can´t meet the demand, consequently it is difficult to finish positioning. In this paper, resolution positioning is first done, and then the positioning is computed by matching with the historical surface characteristics. Then the result is viewed correct and target function is established in order to make the values from resolution positioning approach to the correct values, at last the positioning is finished.
