Location system
First Claim
1. A method for determining location of an object, comprising the steps of:
- identifying receivers that received a signal from a transmitter;
generating one or more line segments connecting the identified receivers;
determining zones around identified receivers;
generating lines through intersections of zones and the one or more lines;
designating the area defined by lines as the potential target area; and
estimating a target location within the potential target area.

Abstract
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.
