摘　　要：随着GPS技术的广泛应用,坐标系统转换问题在测绘工程中的应用越来越广泛.运用布尔莎公式推导出了不同大地坐标系间的精确坐标转换模型———大地坐标微分公式,纠正了目前一些文献中存在的错误,它可以大大提高坐标转换的计算精度,具有一定实用价值.With the extensive application of GPS technique, the transformation model between two geodetic coordinate systems, geodetic coordinates formulae by differential method, which is carried out by the seven-parameter similarity transformation model and some well-known formulae such as Bursa-Wolf and Molodensky-Badekas models etc. In this study, a complete Bursa-Wolf equation, which has rectified errors in some papers is given. The precision and accuracy of coordinates transformation is improved enormously and is valuable to apply.

关 键 词：大地坐标系 坐标转换 尺度 旋转参数
