In a pioneering experiment, the United Kingdom’s Royal Navy has conducted a trial of a new quantum navigation solution on board the cargo ship, Hurst Point. This initiative is the culmination of a collaboration between the Office for the Chief Technology Officer (OCTO), scientists from the University of Birmingham (UoB), and the Defence Science and Technology Laboratory (Dstl), an executive agency within the UK Ministry of Defence (MoD).
The innovative experiment aims to harness the power of quantum mechanics to revolutionise navigation tools at sea. Quantum navigation has the potential to create an advanced positioning and navigation system that is not reliant on a global positioning system, making it less susceptible to disruptions such as jamming, imitation, or other forms of sabotage.
So, how does this new technology work? It involves the use of ultra-cold atoms to make highly accurate measurements. When these atoms are cooled to extremely low temperatures, they exhibit wave-like properties. As the atoms move through the sensor, a series of laser pulses form an ‘optical ruler’, allowing the acceleration of the atoms to be precisely measured. The technology also measures an object’s speed changes over time and combines this with rotation measurements and the object’s initial position to calculate its current location.
By taking this technology to sea, the UK Royal Navy and its partners were able to assess the effects of ship vibration, motion, and acceleration. This will pave the way for further advancements in quantum mechanics as navigation systems.
According to Chester Butterworth, deputy chief technology officer and MoD project lead, “In this experiment, we are advancing novel navigational techniques toward a fully resilient satellite free capability.”
An analysis by GlobalData highlights the potential of quantum technology to bring transformative change in defence. Quantum computing has the capability to significantly enhance the accuracy of precision navigation technologies and operational synchronicity. It can also improve the reliability of inertial navigation systems, ultimately helping forces detect navigational system deception, jamming, and spoofing more efficiently.
The report by GlobalData also emphasises how submarines, particularly nuclear-powered ballistic missile submarines like the future Vanguard class, would greatly benefit from quantum inertial navigation. This advancement would enhance their stealth profiles and nuclear deterrence capabilities.
The successful trial of the quantum navigation solution by the UK Royal Navy is indeed a significant step towards leveraging cutting-edge technology for enhanced navigational capabilities at sea.
