The Royal Navy has successfully trialled a quantum navigation system that can pinpoint a ship’s location without requiring GPS, according to Sky News. Developed by physicists from Imperial College in London, the system uses atomic properties to achieve more precise measurements of an object’s movement than conventional techniques. GPS can be jammed or suffer malfunctions, but the quantum system is resistant to interference, the navy said. Although it has not revealed the technology’s full potential, Sky News suggested submarines could use it under water.
