摘要
考虑资源三号卫星轨道、姿态数据和光学传感器内部结构,构建合适的内方位模型和外方位模型描述内方位元素和外方位元素的误差变化,选取合适的平差模型进行自检校区域网平差。实验结果表明正确的平差模型能显著提高资源三号卫星的立体几何定位精度。
Considering the orbit, angle data and the internal structure of the ZY03 optical sensor, an appropriate inner and exterior model was constructed to describe the variation of the err. Then an approved block model was chosen to make ge ometry calibration. Experimental results proved that the appropriate block model parameters could get a good stereo loca- tion precision for ZY03.
