A location system comprises a location determining module adapted to receive a first signal and a second signal. The location determining module is adapted to associate one of the signals with the other signal provided the first and second signals are received within a selected time period of each other.

Location system using a first signal to gate a second signal

Systems and methods for allowing the location of transmitter to be determined (approximated) without requiring its distance from a receiver to be precisely known. Methods for determining a location of a transmitter without precise distance calculations. In one embodiment, a method is disclosed having the steps of: for a receiver, estimate a first zone a first transmitter is in; for remaining receivers that can receive a given transmitter, each estimate a second zone a first transmitter is in; and determine if there are overlaps in any of the zones. In another embodiment a potential target area is defined wherein the location of a transmitter can estimated.
