Maritime's GPS Woes May Have a Quantum Gravity Fix: Valour

Given increasing GPS signal jamming and spoofing against merchant ships, now might be the time to shift to quantum gravity measurement for navigation, Valour Consultancy blogged Wednesday. Quantum gravity readings provide better accuracy than GPS, but the technology isn't ready for large-scale production, Valour said. It predicted that it will likely be five or so years before commercially available quantum gravity navigation aids are available. However, global navigation satellite systems' vulnerabilities are "unacceptable for world trade, so alternative solutions are almost mandatory."
