Abstract (en)
[origin: EP0660205A1] According to this method the longitude of the place at which one is located on the surface of the Earth is determined by comparing the local time with the time of a reference time zone, and the latitude of the place at which one is located is determined by measuring the inclination of the Earth's magnetic field with respect to the horizontal. <IMAGE>
