Ever noticed that GPS navigation doesn't work well underground? Now there's an alternative navigation system that uses particles produced by cosmic rays from space.
Now, Tanaka and his colleagues have developed a wireless version of the technology, dubbed the muometric wireless navigation system .In the first real-world test of MuWNS, researchers placed four reference detectors on a building’s sixth floor, while someone walked with a receiver detector around the basement.
time taken for the muons to pass between the reference detectors and the receiver detector in the basement, as well as their angle.Sign up to newsletter The team found that MuWNS could track the person in the basement with an accuracy of between 2 to 25 metres, which is comparable to GPS. That is enough to make the system useful for providing navigation to vehicles in tunnels or perhaps one day to find survivors in rubble after earthquakes or cyclones, says Tanaka.
“It is intriguing to see muons being used in a prototype positioning system which claims quite a high accuracy,” says at the University of Oxford. “This new technique could find applications in certain specialised environments.”
