Rising precision demands and GPS/GNSS vulnerabilities are driving the urgent need for secure, reliable synchronization Adtran’s new OSA 3300 Super HP and OSA 3350 Super ePRC+ meet the need for ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...
