Systems, methods, and apparatus to determine physical location and routing within a field of low power beacons
First Claim
1. A position location system, comprising:
- a receiver to receive a plurality of broadcast signals, each of the plurality of received signals associated with an originating one of a plurality of beacons;
a processor that;
determines an initial receiver location relative to locations of at least some of the plurality of beacons;
determines a vector quantity associated with each of the plurality of received broadcast signals to provide a respective plurality of vector quantities;
determines an updated receiver location based on summing the plurality of vector quantities;
generates an output indicative of the updated receiver location.

Abstract
A non-time of flight or time of arrival position location system for accurate determination of a user'"'"'s location in an enclosed, indoor, or covered environment can include a number of beacons mounted in an arrangement within the environment. Each of the beacons is mounted in a known location and transmits a broadcast signal containing a unique identifier that identifies the originating beacon. A handheld electronic device including a receiver and a communicably coupled processor can receive broadcast signals from at least some of the number of beacons, iteratively determine a vector quantity corresponding to each of the received signals, and sum the resultant vector quantities to determine an updated position. The iterative process can be repeated until consecutive iterations yield an updated position that falls within a defined threshold.
