UK Experiments With Light-Based Atomic Clocks for GPS-Free Navigation

The UK is experimenting with using light waves to tell time, taking early steps beyond traditional clocks for military applications.

Recent trials by the Defence Science and Technology Laboratory (Dstl) focused on atomic clocks that measure time via light waves rather than physical vibrations.

Researchers tested both individual components and complete devices, leaving them unattended for extended periods to simulate real deployment conditions on ships, submarines, and other military settings.
