Cosmic-ray muons: new technology to guide underground pathways! Monday June 26th, 2023By Tokio X'press GPS, Communication Underground navigation with cosmic-ray muon : The red line is the route taken by the “navigated person”, the white line is the route recorded by MuWNS ©2023 K.M. Tanaka Cosmic-ray muons: new technology to guide underground pathways! ーNavigate where GPS cannot be usedー Report from the University of Tokyo Research News (June 16, 2023) Demonstration of cosmic ray muons: For the first time in the world, we have demonstrated that “ultrafast muon particles can be used to wirelessly guide underground”. Using a “muon detection ground station synchronized with an underground muon detection receiver”. A researcher at the University of Tokyo measured “the position of the receiver in the basement of a six-story building.” University of Tokyo Muographics: Professor Hiroyuki Tanaka Muons can see deep into volcanoes, see through pyramids, and observe cyclones. Muons are constantly descending at 10,000 per square meter per minute. Cosmic ray muons always move at the same speed regardless of the matter they pass through. Muometric Positioning System (muPS): This works underground, indoors and even underwater. On the ground he used four muon detection reference stations to calculate the coordinates of the underground muon detection receiver. In the latest research, a high-precision quartz clock synchronized the ground station and the receiver. Uses high-precision quartz watches: The coordinates of the receiver are determined by the synchronous clock used for muon time-of-flight measurement. The new system is called the Mumetric Wireless Navigation System (MuWNS). https://www.u-tokyo.ac.jp/focus/en/press/z0508_00291.html Radio Muometric Navigation System (MuWNS): MuWNS enables indoor and underground navigation. The accuracy of the prototype MuWNS surpassed GPS single-point positioning. https://www.sciencedirect.com/science/article/pii/S2589004223010775 More from tokioX : NEC: Developing a power amplifier for the 150GHz band!
