Abstract
A system and method for locating an object uses a plurality of tag signal readers that receive wireless tag signals from a tag transmitter coupled with an object to be located. The tag signals include data indicating the identity of the object to which the tag transmitter is coupled. Each tag signal reader includes a global positioning system receiver associated therewith for determining the location of a tag signal reader. A wireless transmitter transmits a wireless data signal incorporating the wireless tag signal and location of the tag signal reader to a location processor, which receives the wireless data signals and determines which tag signals are first-to-arrive signals and conducts differentiation of the first-to-arrive signals to locate a tag transmitter and object coupled therewith.
