🧭 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?

Search Instagram/Facebook: “Q-CTRL MV Sycamore” for high-engagement clips Sources & 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.

The device uses lasers to cool atoms to extremely low temperatures, and then measures the quantum wave properties of those atoms as they respond to acceleration. #QuantumCompass #GPS engadget.com/2018/11/11/quan…
