Locations and distances are calculated using the World Geodetic System 1984 (WGS-84) ellipsoid. The WGS84 is an earth fixed global reference frame, including an earth model. It is described by a set of primary and secondary parameters. The primary parameters define the shape of an earth ellipsoid, its angular velocity, and the earth mass that ...
