基于Bowring公式的大地纬度两种高精度解法

Two High-Precision Solutions for Geodetic Latitude Based on Bowring Formula

为了提高大地纬度的解算精度,以Bowring 1976公式为基础,通过减小归化纬度的偏差,给出两种大地经纬度解法,使得解算精度从10-3″量级分别提高到不低于10-10″、10-14″量级。

In order to improve the accuracy of geodetic latitude calculation,based on the Bowring 1976 formula and by reducing the deviation of normalized latitude,this paper proposes two methods for geodetic latitude calcula⁃tion,which increase the accuracy of geodetic latitude calculation from the order of 10-3"to no less than 10-10"and 10-14",respectively.
