摘要
介绍了嵌套系数法解算大地主题问题的原理和公式;并以详尽的算例对该方法进行了实验和分析,与贝塞尔方法以及高斯平均约数算法相比较,指出该算法是一种适用于任意大地距离的高精度算法,并且不存在奇异问题。
This paper introduces a compact formulate for the direct and inverse solutions of geodesics of any length.The main feature of the new formulate is the use of nested equations for elliptic terms.Then some examples are given to compare with the traditional algorithm.It testified that the improved algorithm has the advantages of fitting arbitrary distance,easy computing and programming.
