sci.geodetic-to-ecef Calculator
Converts between geodetic coordinates (latitude, longitude, height) and ECEF Cartesian coordinates using the WGS84 ellipsoid. WGS84 defines Earth's semi-major axis as 6,378,137 m and flattening as 1/298.257 — GPS receivers use this conversion internally for all position calculations.
