🧭 Australia built a quantum compass that navigates without GPS — even underwater or when signals are jammed.
Australian quantum company Q-CTRL, working with the Australian Defence Force, has successfully trialled a revolutionary quantum-assured navigation system using ultra-sensitive gravimeters.
These sensors detect tiny variations in Earth’s gravity and magnetic fields to determine position — no satellites needed.
In real-world tests on the Royal Australian Navy’s MV Sycamore, the system ran continuously for over 144 hours in maritime conditions. Airborne trials achieved GPS-like accuracy of just 4 meters over distances up to 700 km — up to 100x better than traditional inertial backups in contested environments.
It works underground, underwater, and during GPS jamming or spoofing — critical for stealth operations, including potential use on Australia’s future AUKUS submarines.
The breakthrough lies in Q-CTRL’s software that “ruggedizes” delicate quantum hardware to survive real-world vibrations and motion.
This isn’t lab theory anymore — it’s moving toward real defence deployment in a world where GPS can no longer be fully trusted.
How soon do you think quantum navigation will go civilian?

Verified Details (March 2026):
•Q-CTRL’s Ironstone Opal system (software-ruggedized quantum gravimeter) completed successful 2025 maritime trials on MV Sycamore (>144 hours continuous operation, no human intervention).
•Airborne trials: ~4m accuracy over 700 km flights (up to 100x improvement over conventional INS in some metrics).
•Designed for GPS-denied environments (underwater, underground, jammed zones) and supports AUKUS quantum tech priorities.
•No public confirmation of exact “1 meter after 24 hours” or direct submarine deployment yet — these are advanced trials, not full operational rollout.
