ECEF Co-ordinate Frame

The ECEF (Earth-centred earth-fixed) co-ordinate frame is a Cartesian co-ordinate
frame used to represent absolute positions on the Earth. Its origin is at the centre of
the Earth. ECEF is an alternative to the geodetic co-ordinate frame. It is represented
by the three axes X, Y and Z which are presented graphically in Illustration 6. ECEF
positions can be retrieved from Advanced Navigation products however the geodetic
system is used as the default.
