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