Drone strikes deep into Russian territory have exposed a glaring weakness in modern warfare. GPS signals, long taken for granted, now prove easy to jam or spoof. Ukrainian forces have adapted. Russian defenses have countered. The result is a frantic push for alternatives that don’t rely on satellites.
At the Farnborough International Airshow this week, several companies showed prototypes designed exactly for that reality. One Australian firm stood out. Q-CTRL demonstrated what it calls the world’s first airworthiness-qualified quantum navigation system. The device, known as Ironstone Opal, promises GPS-like accuracy without any satellite connection. It measures variations in Earth’s magnetic and gravitational fields. Those readings get matched against detailed maps. Position locks in. No signals from space required.
“The technology is not a replacement for GPS,” said Charlie Burnard, Q-CTRL’s global head of government engagement, in reporting by The Next Web. “It is a reliable, resilient backup for environments where GPS or even other navigation modalities just don’t operate.”
Short. Direct. And critical in contested airspace.
The urgency comes from Ukraine. Russian electronic warfare units have blanketed front lines with jammers. Early in the conflict, Ukrainian drones supplied by Quantum Systems crashed repeatedly. Russian jamming overwhelmed their links. Later models added frequency hopping. They improved. Yet the cat-and-mouse game continues. Long-range strikes on oil refineries and other targets show both sides probing deeper into defended zones. There, GPS denial becomes routine. The margin between success and failure narrows to meters.
Q-CTRL isn’t alone. Israeli company ASIO relies on onboard cameras and image processing to track position. American firm ANELLO Photonics offers a fiber-optic laser gyroscope the size of a matchbook. No moving parts. It pairs with traditional inertial systems to correct drift over time. Ukrainian startup Sine developed a time-of-flight approach. All aim to solve the same problem. Inertial navigation alone drifts too much for precise strikes. Quantum and optical methods bound that error.
Recent partnerships signal acceleration. ANELLO and Q-CTRL announced collaboration earlier this year to combine silicon photonics with quantum sensors for continuous positioning. The joint effort targets UAVs operating where GNSS signals vanish. Posts on X from industry watchers in March 2026 highlighted the pairing as a key step for bounded accuracy in jammed environments.
Military interest runs high. The Pentagon has grown alarmed at GPS dependence. A November 2025 Wall Street Journal report detailed how new quantum devices could navigate without satellites and without jamming risk. Test flights in Australia involved small planes carrying Q-CTRL hardware. Lasers probed atoms to read magnetic fields. Data compared to maps gave location fixes. Engineers prepared the gear on the tarmac at Griffith. Results encouraged further investment.
Airbus has explored similar ideas. Its Acubed innovation unit teamed with SandboxAQ. They flew a quantum sensor aboard a Beechcraft Baron. The toaster-sized box used lasers and a GPU to detect magnetic anomalies in the Earth’s crust. “The magnetic pull in the Earth’s crust could offer a novel solution,” the project noted, according to a July 2025 Wall Street Journal article. While focused on commercial aviation, the implications for uncrewed systems are clear. Drones could adopt miniaturized versions for autonomy in denied areas.
Power and size still pose hurdles. Early quantum hardware filled rooms. Today’s versions shrink toward drone-compatible footprints. Q-CTRL claims tight size, weight and power demands suitable for uncrewed aerial vehicles. That matters. Heavy sensors cut payload or flight time. Battlefield operators won’t accept trade-offs that reduce range or endurance.
But progress is real. The UK conducted quantum navigation test flights earlier in 2026. A portable quantum accelerometer prototype appeared years ago from Imperial College London and M Squared. French company iXblue has worked on quantum gyroscopes. These efforts build on decades of laboratory work. Atoms behave as both particles and waves under quantum rules. Acceleration changes those wave properties. Sensors detect the shifts with extreme precision. Drift stays minimal over hours.
Commercial interest spreads beyond defense. Autonomous cars could use the tech in urban canyons where GPS fails. Commercial airliners might gain backup during solar storms or deliberate interference. Q-CTRL eyes multiple markets. Its executives have spoken of equipping every Airbus aircraft eventually. A July 2026 report from AINonline captured that ambition at Farnborough.
Yet challenges remain. Maps must be accurate and up to date. Magnetic fields shift slowly but measurably. Gravitational anomalies require high-resolution surveys. Initial deployment will likely pair quantum sensors with other aids. Visual odometry. Laser ranging. Even fiber-optic tethers for short missions. Russia has already countered fiber-guided drones by entangling their control lines.
The broader electronic warfare picture grows more complex. Civilian flights face disruption. A 2024 Financial Times investigation showed GPS warfare spilling into commercial airspace. Aircraft divert. Ships lose position. The same vulnerabilities that plague drones affect everything.
So investment pours in. ZenaTech announced defense-focused quantum navigation for its ZenaDrone 1000 platform in early 2026. The system targets GPS-denied operations for surveillance and border patrol. Company updates on X highlighted compliance with U.S. defense standards. Other startups in India and Israel pursue parallel tracks. Zuppa and QuBeats partnered on quantum-assured solutions for unmanned systems. Activity on X reflects scattered but growing excitement.
No one claims these systems will eliminate GPS. They augment it. When signals disappear, the backup takes over. Accuracy must match mission needs. A few meters might suffice for cargo delivery. Centimeter precision is required for precision strikes. Current inertial systems drift by hundreds of meters per hour. Quantum versions promise orders of magnitude better performance.
The Farnborough displays underscored the shift. Attendees saw live demonstrations. Ironstone Opal drew defense officials. Its airworthiness qualification sets it apart. Regulators have cleared it for flight. That milestone opens doors faster than pure laboratory prototypes.
Battlefield lessons from Ukraine drive the timeline. What once seemed like science fiction now appears on trade show floors. Operators who master jam-resistant navigation gain decisive advantage. Those who don’t risk mission failure. The race is on.
And the technology keeps improving. Smaller. Cheaper. More reliable. Within years, quantum backups could become standard on military drones. Civilian applications will follow. The satellite layer remains useful. But dependence on it alone looks increasingly risky.
Defense contractors take notice. Larger primes scout these startups. Acquisition talks circulate. The ones that deliver working systems in contested environments will command attention. Q-CTRL, ANELLO, ASIO. Their names surface repeatedly in recent discussions.
The next phase will test them under real electronic attack. Not trade show simulations. Actual jamming. Real missions. Success there will decide who leads the next generation of autonomous systems.
