The gist
Q-CTRL's Ironstone Opal achieved one nautical mile accuracy in GPS-free quantum navigation trial at sea.
Quantum navigation resists jamming, offering a resilient alternative for maritime operations.
Background
GPS jamming and spoofing have become a growing threat, with nearly a million jamming events recorded globally in early 2026, heavily impacting maritime vessels. In response, Q-CTRL has developed Ironstone Opal, a quantum gravimetric navigation system that uses Earth's gravity signatures to determine position without satellite signals. The system was tested in a maritime field trial off Australia's East Coast, marking the first successful open demonstration of GPS-free quantum navigation at sea.
How it unfolded
- Apr 2025Ironstone Opal demonstrated GNSS-free MagNav in ground and airborne trials, outperforming conventional GPS by up to 100 times.
- Aug 27, 2026Q-CTRL announced the world's first GPS-free quantum gravimetric navigation demonstration in a maritime field trial off Australia's East Coast, achieving one nautical mile accuracy.
- Aug 28, 2026The news was widely reported, highlighting the system's potential to counter GPS jamming and spoofing threats.
Who’s saying what
- Official
- Q-CTRL CEO Michael J. Biercuk stated that adversaries are not waiting, and quantum technology must be leveraged for defense advantage now.
- Expert
- Q-CTRL claims gravity sensing and map matching is the only passive alternative navigation technology that is global and impossible to jam or spoof.
Still unverified
The claimed accuracy and performance are based on Q-CTRL's own press release and have not been independently verified.
