Description
Muometric positioning is a novel positioning technique with envisioned applications in indoor, underground and underwater navigation. The technique exploits the highly penetrative cosmic-ray muons, that can penetrate kilometers of rock or water and have low angular scattering even on large distances.
A muometric positioning system includes a receiver detector with unknown position and reference detectors with known positions. The goal is to find the position of the receiver detector measuring muons crossing both a reference and the receiver detector. Various possible realizations of such muometric positioning system have been proposed and investigated in recent years, from the first prototype based on the measurement of the time of flight of muons with wire based communication between the detectors, to the most recently developed wireless system built from MWPCs and utilizing the direction vector of cosmic muons, capable of reaching centimeter level positioning accuracy in 2
dimensions.
This system was further developed and now consists of two reference detectors with angular resolution of ∼ 30 mrad, capable of 3 dimensional positioning. We present the first demonstration of 3 dimensional positioning with this system using a Kalman filter based algorithm to position and follow the movement of the receiver detector. With the proposed hardware and algorithm ∼ 20 cm positioning accuracy was reached with a distance of ∼ 7 m between the receiver and reference detectors.
