With Quantum Devices, UK Army Hopes to Overcome GPS Vulnerabilities

Civilian researchers working with the U.K. military are hoping their advanced research on quantum timing, navigation and sensing devices—machines that manipulate the properties of subatomic particles—will help plug a serious and growing threat to the operational capabilities of Her Majesty’s Armed Forces: their over reliance on vulnerable global positioning system—or GPS—satellites, whose signals can be weak, and which are easy to jam.If they’re successful, scientists at Britain’s Defence Science and Technology Laboratory say their devices will enable ground troops to ‘see’ through walls, and submarine crews—who cannot use GPS underwater—to determine their precise location at all times. DSTL is the UK military’s R&D arm, which promises to develop “battle-winning technologies” by tapping the country’s science and technology community.
