| Abstract: | Based on ZY-3＇s rigorous sensor model, a method for testing the systemic error of attitude quaternion of ZY3 satellite is established. Then experiments of resolving the systemic error of attitude quaternion with different number of GCPs are done on two views of image. The result shows the direct positioning accuracy can be substantially improved after the systemic error of attitude is corrected. It also verifies the validity and effectiveness of proposed method. |
