ABSTRACT:
According to this method the longitude of the place where one is situated 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 where one is situated is determined by measuring the inclination of the earth's magnetic field in relation to the horizontal.
