| 摘 要： | 对于高斯正反算来说,首先要计算子午线弧长和底点纬度,从根本上讲,子午线弧长和底点纬度的精度决定着高斯正反算结果的精度。文章参考了一些文献和书籍,借助其成果,实现了不同椭球的较高精度的高斯正反算解算程序。

| Abstract: | When doing the Gauss Positive and Inverse Calculation,we must first calculate the radial arc length and the end point latitude,fundamentally speaking,the end point latitude meridian arc length and the accuracy of the Gaussian determines the precision of the calculation results.This paper referred to some literature and books,with their achievements,we implemented a higher accuracy program for Gauss Positive and Inverse Calculation in different ellipsoids. |

| Keywords: | different ellipsoids Gauss positive and inverse calculation higher precision |
