Abstract: The location of a transmitter can be determined by accurately measuring the elapsed time that it takes for a signal to propagate from a transmission source to a plurality of disparate receivers of a known location. By comparing the received transmitted signal to reference signal a range between each receiver and the transmitter can be determined. By intersecting the spheres defined by each range an accurate location of the transmitter can be obtained.
