Abstract
The location of a mobile unit is determined by evaluating the instantaneous distances between an apparatus traveling above the surface of the earth and the mobile unit. The instantaneous distances are determined by measuring the travel time of a plurality of signals and calculating the distance based on the speed of the signal. One of two possible location regions is identified as the region including the location of the mobile unit by observing the motion of the mobile unit resulting from the rotation of the Earth.
