摘要
自检校区域网平差是实现卫星影像高精度定位的常用方法，但存在自检校参数设置困难、参数相关性问题无法很好解决等问题。本文探讨了一种基于RFM区域网平差的卫星影像定位方法，它避开了使用卫星成像的复杂物理几何模型，无须设置自检校参数，使得平差的过程得以简化，且定位精度高。理论分析和初步试验证明了该方法的有效性和精确性。
Self - calibration block adjustment is a method commonly used in the high - precision geometrical positioning of satellite images, but there still exist problems of self - calibration parameter setting and parameter correlation. A geometric posi- tioning method based on RFM block adjustment is presented in this paper. Without using complicated physical geometry model of satellite imaging or setting self - calibration parameters, the method can simplify the adjustment process and achieve higher preci- sion. The effectiveness and accuracy of the method is proved by theoretical analysis and preliminary test.
