摘要
依据高精度子午线长度正算公式,给出了子午线弧长反算公式基于迭代算法程序语言的具体实现,计算出了常用4种椭球的高精度系数值,然后进行了正反算的验证。
Based on the calculation formula of high precision meridian length,the paper presents meridian arc length formula.Based on the realization of iterative algorithm,four commonly used high precision coefficient values of ellipsoid are calculated and positive and inverse calculation is verified.
