Q-CTRL has successfully demonstrated a GPS-free navigation system using quantum gravimetry that achieves one nautical mile accuracy by mapping Earth's gravity signatures. This development addresses critical vulnerabilities in maritime operations caused by widespread GPS jamming and spoofing, offering a passive, unjammable alternative for autonomous positioning. The technology represents a significant step forward in resilient navigation infrastructure, particularly where detailed gravity maps are available over open oceans.
Can quantum sensors map Earth’s gravity for navigation? Q-CTRL says yes

Q-CTRL demonstrated GPS-free navigation using a quantum gravimeter in the Coral Sea, achieving one nautical mile positioning accuracy.
Approximately 978,000 GPS jamming events were recorded globally in the first quarter of 2026, with 98% concentrated in the Middle East and impacting over 1,100 vessels; in response, Q-CTRL has demonstrated the world’s first GPS-free quantum gravimetric navigation system in a maritime field trial off Australia’s East Coast, the company says. The company achieved one nautical mile positioning accuracy using its new Ironstone Opal system,…
