ABSTRACT:
A method and system for determining the location of a mobile transmitting device that uses three dimensional location coordinates to triangulate the location using a time difference of arrival method, with diminishing errors, error correction and which takes advantage of global positioning systems without the requirement of highly accurate clocks in the mobile transmitting device and the base stations.
