Q-CTRL Demonstrates First GPS-Free Quantum Gravimetric Maritime Navigation in Coral Sea Field Trial

Quantum infrastructure software firm Q-CTRL has announced the world’s first open-water field demonstration of a GPS-free, quantum-gravimetric maritime navigation system. Tested aboard a 29-meter surface vessel in the Coral Sea off Australia’s eastern coast, the company’s Ironstone Opal navigation platform achieved bounded 1-nautical-mile positioning accuracy without satellite signals, outperforming standard navigation-grade inertial backups by more […]
