› A new navigation system called muometric positioning system (muPS) utilizes subatomic particles called muons to track locations indoors, underground, and underwater, where GPS is ineffective. Instead of relying on satellite signals, muPS requires a receiver and multiple "reference detectors" to triangulate the receiver's location. Currently, the accuracy of muPS ranges from 2 to 25 meters. However, by incorporating chip-scale atomic clocks, the potential exists to achieve real-time measurements with accuracy down to one meter.
