The Global Positioning System (GPS), the Internet and many defense-critical applications for example—demand exceptionally precise time and frequency standards. Today’s systems, however, rely on 1950s ...

China has quietly taken a decisive step in the new space race by building what it calls the first software system capable of ...

Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for ...

BS: beam splitter. FM: Faraday mirror. PM: phase modulator. Att: attenuator. The solid red lines represent the fiber links. The dotted blue lines represent electromagnetic signal links. Quantum key ...

Precise timing sits quietly at the heart of modern systems. Communications networks, military command chains, financial ...

TOKYO--(BUSINESS WIRE)--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today expanded its communication timing portfolio with three new low phase ...

Time-sensitive networks (TSN) in Ethernet are improving computer-based measurements from sub-microsecond to sub-nanosecond precision. By using message-based protocols that synchronize clocks, it is ...

In a network containing multiple nodes, the need for synchronization between the various nodes is not just instrumental but also a complicated and highly complex process. This process becomes even ...

The 350-year-old mystery of why pendulum clocks hanging from the same wall can influence each other and synchronize over time may hold even more secrets than previously thought, researchers say.
