NV Diamonds: Enhancing Inertial Navigation with Quantum Magnetometers
By Joel Louette – Director of Business Development, Emerging Markets
The increasing vulnerability of traditional GPS, as highlighted by Flightradar24 regarding jamming and spoofing of Global Navigation Satellite Systems (GNSS), is driving the exploration of alternative navigation technologies.
Envision a world where critical navigation remains steadfast, even when GPS signals falter, are jammed, or become entirely unavailable. Picture submarines navigating the ocean’s depths with unwavering precision. Imagine aircraft maintaining accurate course over vast distances, secured against potential GPS manipulation. This isn’t science fiction; it’s the promise of nitrogen-vacancy (NV) diamond quantum magnetometers, enhancing inertial navigation, particularly in environments where traditional GPS reliance is compromised.
But first, what exactly is inertial navigation?
Essentially, it’s a self-contained navigation method that uses accelerometers and gyroscopes to track an object’s motion. By knowing your starting point, speed, and direction, an inertial navigation system (INS) calculates your current position. However, traditional INS systems suffer from a critical flaw: error accumulation, or “drift,” which increases over time. For long journeys, or in environments where external signals are unavailable, this drift can become significant, leading to inaccuracies and requiring regular recalibration based on a known location.
Enter NV diamond quantum magnetometers. These remarkable sensors leverage the quantum properties of nitrogen-vacancy centers in diamonds to measure magnetic fields with astonishing precision. Unlike traditional sensors, they boast inherent stability and are immune to environmental interference. Crucially, they can be used to correct the errors of the accelerometers and gyroscopes in an INS, significantly reducing drift and enhancing accuracy. This capability is further amplified by the availability of precise magnetic field maps of the earth, which allow the quantum magnetometers to accurately determine orientation and position by comparing their measurements to the known magnetic field. Moreover, thanks to their quantum nature and their ability to operate at room temperature, they can be miniaturized, leading to much smaller INS systems. This miniaturization, coupled with the reliance on the earth’s magnetic field, is a key factor in the development of advanced inertial navigation systems.
Civil aviation applications
Civil aviation is also recognizing the benefits of quantum-enhanced inertial navigation. Other companies like Phasor Quantum offer compact systems using diamond-based vector magnetic field sensors, providing persistent quantum-assured navigation for undersea, surface, and airborne navigation without relying on GPS.
Military applications
The potential of quantum magnetometers for enhanced military navigation is being actively explored. DARPA’s Robust Quantum Sensors (RoQS) program aims to develop robust quantum sensors for military platforms, offering a resilient alternative to GPS in contested environments. Lockheed Martin’s “Dark Ice” project, in collaboration with Element Six, is an example of that technology. Research institutions like MIT Lincoln Laboratory are also actively developing diamond magnetometers, leveraging the unique sensitivity of NV centers to magnetic fields for precise navigation.
The benefits of NV diamond quantum magnetometers for inertial navigation are clear: increased accuracy and stability, reduced size and weight, and enhanced reliability in GPS-denied or compromised environments.
The future of navigation is quantum, and because of their mass deployability, NV diamonds are leading the charge. They will equip planes, ships, drones, and robots. CIL is proud to be at the forefront of this development, providing the high-quality quantum 12C methane and 15N nitrogen necessary for their synthesis.
Stay tuned as we delve deeper into the fascinating world of quantum diamonds and their applications.
