An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...

Precision time synchronisation lies at the heart of modern networked systems, underpinning the reliable operation of critical infrastructures ranging from power grids and telecommunications to ...

Scientists have demonstrated a capability long sought by physicists: transmitting extremely precise time signals through the air between far-flung locations at powers that are compatible with future ...

While computers manage many things with extreme precision, they have surprising difficulty keeping track of time. It’s pretty much impossible for a computer to keep exact time, although accuracy can ...

The need for more accurate time synchronization within a distributed system. The challenges of using synchronized time provided by the Precision Time Protocol (PTP) in application software and the ...

The bc635PCI-V2 and the GPS-referenced bc637PCI-V2 PCI frequency processor modules provide precise time and frequency references to host computers and peripheral data acquisition systems. They provide ...
