高精度GPS水准高程求解算法研究

RESEARCH ON HIGH ACCURACY METHOD IN GPS LEVEL HEIGHT DETERMINATION

为了改善 GPS大地高向正常高转换的精度和计算速度 ,坐标转换、顾及非格网数据考虑地形改正的几何方法和龙贝格加速积分法被采用 ,实践验证 。

In order to improve the accuracy and speed of transferring geodesy height to normal height, the coordinate transfer, terrain correction and high precision integral arithmetic are advised in this paper. The result is satisfying.
