空间直角坐标向大地坐标转换的新算法
A New Algorithm for Transforming from Cartesian to Geodetic Coordinates
-
摘要: 利用牛顿迭代法求解一元四次方程,实现空间直角坐标向大地坐标的转换,并分别给出两种不同的迭代初值,一种适合空间所有区域,一种适合绝大部分区域。同已有方法的比较说明,所提出的算法快速可靠。Abstract: A new algorithm for computing geodetic coordinates from Cartesian coordinateswais is derived by solving a modification of Levin's quartic equation with Newton's iteration from two different initial values.Experiments with two given initial values show that the new algorithm is sufficiently precise,fast,and stable.
