Navigation via cosmic ray muons could supplement GPS in high latitudes, as well as working underwater and underground.
The US Office of Naval Research (ONR) has awarded a contract to UK company Geoptic Infrastructure Investigations to demonstrate navigation in the Arctic where GPS coverage is poor due to positioning of GPS satellites run by the US military, which are mostly at lower latitudes.
The firm’s Muometric Positioning System (muPS) uses muons made by cosmic rays instead of the radio signals from satellites …
