A navigation system skips GPS, works across air, land, and sea, resists jamming and spoofing, and keeps positioning stable for missions.
Q-CTRL has revealed its quantum navigation system, Ironstone Opal, The company claims the system has already been tested across air, land, and sea, where it demonstrated reliable positioning without relying on GPS.
Ironstone Opal uses quantum sensors and magnetic map matching to provide positioning that does not depend on external signals. This allows it to operate without being affected by jamming or spoofing, which are growing concerns for traditional satellite-based navigation. The system is designed to work in all visibility conditions and meets key aviation performance requirements, positioning it as a backup to GPS. The company also highlights that the system can be integrated into smaller UAVs and deployed internationally without regulatory restrictions tied to export controls.
The technology is being positioned against other GPS alternatives, such as low Earth orbit navigation systems, vision-based approaches, and inertial navigation systems, which each face limitations like signal vulnerability, restricted coverage, or drift over time. In contrast, magnetic navigation works across land and sea and does not rely on external transmissions, making it more resilient in contested environments.
Q-CTRL is also introducing an evaluation kit for Ironstone Opal, allowing aerospace and defense organizations to test the system without modifying existing aircraft or navigation setups. The kit is designed to help users assess its “bounded positioning” capability, which maintains consistent accuracy over time.
The system operates passively, without emitting signals, making it suitable for both commercial aviation and defense use. It is designed to work alongside inertial navigation systems, improving their accuracy and reducing drift. Versions are available for both crewed and uncrewed platforms.
With disruptions to GPS expected to cause significant economic impact, Q-CTRL positions Ironstone Opal as a practical alternative for maintaining reliable navigation in critical applications.
