Britain has achieved a world-first with a series of test flights that show the key technologies of a future quantum navigation system meant to counter one of the most potentially dangerous, yet little discussed, dangers to transportation: GPS jamming and spoofing.
The Threat of GPS Spoofing
GPS has become such an integral part of our lives, with several applications, that it’s easy to take them for granted- that is until you drive into a steep mountain valley or densely wooded forest and lose your satellite signal. That can be quite unsettling as the fuel indicator hangs around empty and you have no idea where the next gas station is.
Quantum Navigation
It’s worse for ships and aircraft, as they confront not just the danger of an unintentional signal failure, but also active jamming and spoofing. Jamming GPS is the same as jamming radio or radar. It’s merely sending a strong transmission that may overpower and drown out the GPS signal. Spoofing, on the other hand, poses a much greater risk. This entails sending out misleading signals to trick a GPS device into thinking it is somewhere else and moving in the wrong direction.[…]
