"Quantum compass" as an alternative to GPS

The UK Department of Defense is investing £ 270 million in developing an alternative to GPS. The novelty will be called " quantum compass ". It is planned to spend 3–5 years on its development, and it will be studied by scientists from the National Physical Laboratory in Porton Down.



The technology is based on the subatomic effect of the Earth’s magnetic field, which is captured by the instrument and allows you to locate anywhere in the world. This new product will completely eliminate the use of satellites or fixed points for sending and receiving signals such as radio masts in navigation.
In addition, without regular debugging and repair, even the most complex navigation system begins to give readings with minor deviations: up to 1 km of inaccuracies can “accumulate” during the day. From this point of view, the new technology seems much more progressive.
Experts note that over time, the “quantum compass” can be used not only in the military, but also in the civilian sphere, for example, in smartphones to replace GPS.
