Royal Navy Tests Quantum Navigation

GPS has changed the way we get around the globe. But if you command a warship, you must think about what you would do if an adversary destroyed or compromised your GPS system. The Royal Navy and Imperial College London think a quantum navigation system might be the answer.


The quantum sensors in question are essentially accelerometers. Unlike conventional accelerometers, though, these devices use ultracold atoms to make very precise measurements using a laser optical ruler, which means they do not drift as rapidly


You can see a Sky News report on the trial below.The tests were done in a rapid prototyping pod carried onboard XV Patrick Blackett, a fitting name for an experimental ship since Lord Blackett was a Nobel laureate and head of the physics department at Imperial College for a decade ending in 1963. The underlying tech came out of the university back in 2018, but making it work in a real-world environment onboard a ship is another matter.
