Using the WGS 84 parameters, my program converts a geographical longitude and latitude into a 3 dimensional vector in the ECEF system (Earth-Centered, Earth-Fixed Cartesian coordinate system which rotates with the earth). But why does it matter? Using the wrong spheroid would give a slightly wrong solution to any navigational problem but not impact the principle. You are not suggesting that your problem can only be solved on a non-spherical earth, are you? Herbert
