摘　　要：根据资源三号卫星严格成像模型,建立姿态四元数系统误差检验模型,通过对登封地区2景影像进行试验,利用不同控制点数量求解姿态四元数系统误差,将姿态进行系统误差改正后,可以使卫星直接定位精度大幅提高,验证了姿态四元数系统误差检验方法的正确性和有效性。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.
