Description: The n-vector framework uses the normal vector to the Earth
        ellipsoid (called n-vector) as a non-singular position
        representation that turns out to be very convenient for
        practical position calculations.  The n-vector is simple to use
        and gives exact answers for all global positions, and all
        distances, for both ellipsoidal and spherical Earth models.
