Sphere – To – Spheroid Comparison – Numerical Analysis

Abstract

Differences of orthodromic distances calculated on the sphere in comparison to the spheroid are numerically analyzed in the full range of departure point latitudes, courses over the ground and orthodromic distances for the global and limited range of latitudes. Optimum solutions for the radii of the sphere are provided.
