Atomic Clocks

This article discusses the use of precision oscillators in synchronized timing solutions, covering: Network Time Protocol Oscillators For Reference Clock Redundancy Types of Oscillators: Rubidium, OCXO, TCXO, Quartz Summary The Network Time Protocol, or NTP as it is more commonly known, is a computer protocol developed to distribute accurate time information across a computer network. Developed in the 1980′s […]

There are a number of national time and frequency transmissions broadcast from a number of countries around the world. In the US, the WWVB signal is transmitted from Colorado. In Europe, the MSF and DCF-77 signals are broadcast from Cumbria in the UK and Frankfurt in Germany. All provide encoded time and date information that […]

The MSF-60 atomic clock synchronized radio time transmission is utilised by many NTP Time Server and PC computer systems to provide accurate synchronization of time critical applications. This article describes how the MSF-60 time signal is decoded by NTP Time Server and computer systems to provide an accurate timing reference. The MSF-60 Time Transmitter The […]

Atomic clocks are the most accurate time keeping devices in existence, and use the oscillation of atoms stimulated by an electromagnetic field as a frequency standard for keeping time. There are various types of atomic clock, the most common being Caesium Clocks and Rubidium Clocks, and they are most commonly found in research facilities. Atomic Clocks […]

This article discusses a number of aspects associated with Atomic Clock time references and specifically their use in computer systems and network time synchronization. Topics covered: What is an Atomic Clock? National Time and Frequency Radio Broadcasts Time and the Global Positioning System The Galileo GNSS System Synchronizing Computer Systems and Networks What is an […]
