Abstract
A method is described for tracking the position, orientation and/or guiding a transmitter as it moves through the ground in a region. The transmitter transmits an electromagnetic locating signal received by a detector. The detector, with the transmitter at a start position, receives the signal to produce a first set of electromagnetic data. The transmitter moves to a second position. The detector receives the signal with the transmitter at the second position to produce a second set of electromagnetic data. Absolute positions of the detector and the transmitter are determined within the region using certain information including the first and second sets of electromagnetic data.
