Magnetic Navigation & Detection
In a world increasingly reliant on precise positioning and orientation, quantum navigation emerges as a disruptive solution to one of today’s greatest challenges: navigating when satellite-based navigation solutions fail. At Kwan-tek, we develop next-generation vectorial magnetometers powered by diamond quantum sensors that deliver robust, drift-free, and high-resolution magnetic field measurements — anywhere, anytime.
Why quantum navigation matters
Modern industries depend on precise navigation and detection systems to keep operations safe and efficient. Yet, GNSS (Global Navigation Satellite Systems) signals can be easily blocked or spoofed, and traditional magnetic sensors are vulnerable to temperature drifts, local interference, and limited accuracy.
From aerospace missions operating in GNSS-denied environments to autonomous vehicles and underwater navigation, maintaining a reliable and absolute reference for heading and position is critical. KWAN-TEK’s quantum magnetometers harness the unique properties of NV center diamonds, setting a new standard for resilience, stability, and vectorial measurement precision.
How our quantum magnetometers work
At the heart of our quantum navigation solutions is the nitrogen-vacancy (NV) center — a tiny defect in the diamond lattice that turns a pure crystal into a sensitive quantum sensor. When a diamond containing NV centers is illuminated by laser light and subjected to microwave excitation, it exhibits a photoluminescent response that directly correlates with the local magnetic field.
This enables our vectorial magnetometers to measure the magnitude and direction of Earth’s magnetic field with remarkable stability. Unlike traditional Hall-effect sensors or fluxgates, our quantum diamond sensors are inherently immune to thermal drifts and can deliver an absolute reference measurement — a vital feature for high-precision navigation.
Compact, robust and drift-free
One of the greatest advantages of our NV magnetometers is their compact form factor. This makes them ideal for applications where space is limited and weight must be minimized — such as on drones, satellites, portable devices, and integrated navigation systems.
Because diamonds are among the most robust materials on Earth, our sensors maintain their performance under high pressure, extreme temperatures, or strong vibrations. They can operate continuously without recalibration, providing a stable magnetic reference for attitude and heading reference systems (AHRS), inertial navigation system (INS), and other integrated systems.
Our magnetometers provide a true measurement of the magnetic field vector, ensuring an absolute reference point that does not drift over time or with temperature fluctuations.
NV center diamonds deliver sensitive magnetic field measurements in three directions, enabling precise heading and orientation even in challenging environments.
With a footprint that fits in your hand, our sensors are designed for easy integration into existing navigation hardware, from aerospace systems to autonomous vehicles.
Thanks to the unique properties of diamonds, our magnetometers function reliably at high or low temperatures, under mechanical stress, and in electromagnetic noise.
Diamond quantum sensors can be manufactured at scale with consistent quality, making them an economically viable solution for both industrial and research-grade applications.
By providing a backup or alternative to GNSS, our quantum navigation systems increase resilience against signal denial or spoofing — critical for defense, space, and autonomous systems.
Applications that go beyond limits
Aerospace & Defence
Maintain navigation capabilities in GNSS-denied zones such as polar regions, deep canyons, or contested airspace. Enhance attitude and heading reference for aircraft, drones, or spacecraft with a robust magnetic compass that cannot be jammed.
Autonomous Vehicles & Robotics
Improve positioning accuracy and reliability for drones, unmanned ground vehicles (UGVs), or autonomous underwater vehicles (AUVs). Our vectorial magnetometers enable more robust sensor fusion with inertial measurement units.
Marine & Subsea Navigation
Extend navigation capabilities underwater where GNSS is unavailable. Quantum magnetometers provide a reliable magnetic north reference for AUVs, remotely operated vehicles (ROVs), and underwater positioning systems.
Geophysical Exploration & Surveying
Detect subtle magnetic anomalies for mineral exploration, archaeological surveys, or environmental monitoring with high-resolution, drift-free measurements that outperform traditional magnetic sensors.
Scientific Research & Education
Equip laboratories and universities with cutting-edge tools for studying Earth’s magnetic field or developing new quantum sensing applications. Our systems make quantum physics tangible for students and researchers alike.
