India's indigenous satellite navigation system NavIC faces fresh reliability concerns after IRNSS-1F's atomic clock failure, ...

Atomic clocks are the heart of any satellite navigation system, providing the ultra-precise timing required to determine ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...
