贝塞尔大地反解问题的高效率算法

An Effective Algorithm Based on Bessel's Formula for Inverse Solution of Geodetic Problem

针对目前的贝塞尔大地反解算法中存在的问题 ,设计一种高效率的贝塞尔大地问题反解算法 ,解决了原算法存在的奇异问题 ,不需做繁琐的象限判定 ,计算方便易于编程实现。同时指出贝塞尔投影不是同胚映射 ,不适用于距离太远的大地问题反解。

The authors pointed out some of the limitations of the traditional Bessel's formula-based algorithm of inverse solution of geodetic problem and present a new algorithm to combat such deficiencies. Compared with the traditional algorithm, the new algorithm has the advantages of no oddity, easy computing and programming. We also point out that Bessel's mapping is not an isomorphic mapping, it is impossible to fit to arbitrary distance of inverse solution of geodetic problem.
