Muometric navigation is positioning, navigation and timing using cosmic ray muons and other cosmic particles.
It is possible to determine locations with GNSS satellites with well-known positions and time. GNSS is often used by critically important governmental organizations for navigating ships and planes, but the signals can be easily jammed and spoofed. In 2020 Hiroyuki K.M. Tanaka created an entirely new approach from GNSS that locates the receiver's position with cosmic-ray muons.
Muometric techniques include the muometric positioning system (muPS), the muometric wireless navigation system (MuWNS) or muPS Wireless Navigation System (muWNS), cosmic time synchronizer (CTS) and cosmic time calibrator (CTC).
