US 2017/0285131 A1 · SIGNAL PROPAGATING POSITIONING SYSTEM

Abstract

A computer broadcasts a tier 1 signal from a target device and records transmission data of the broadcast. The computer detects the tier 1 signal at nearby propagator devices and records additional transmission data before determining whether a propagation limit has been reached. Based on not reaching the propagation limit, the computer instructs the nearby propagator devices to broadcast a tier 2 signal. The computer records further transmission data at other nearby propagator devices detecting the tier 2 signal and, again, determines whether the propagation limit has been reached. Based on determining that the propagation limit has been reached, the computer filters outliers from all the transmission data and determines the precise location of the target device. Furthermore, the computer displays the relative location of the target device on one or more devices.

Dependent claims

A method for a signal propagating positioning system, the method comprising:

receiving, by a computer, a request to broadcast a first signal;
instructing, by the computer, a first device to broadcast the first signal;
receiving, by the computer, a first transmission time and a first transmission location associated with the broadcasted first signal;
receiving, by the computer, a first data, wherein the first data includes one or more first detection times and one or more first detection locations from one or more second devices, and wherein receiving the first data is based on the one or more second devices detecting the first signal;
and
determining, by the computer, whether a precise location of the first device can be determined based on the first data.
