Satellite navigation for the NTP time server, atomic clocks are used around the world

Satellite navigation for the NTP time server, atomic clocks are used throughout the world.

We are all accustomed to our clocks in the management of one or two minutes, fast or slow. However, the odd doesn minutes, AOT affect our lives too and we are able to address. However, for some technologies and applications of a much higher level of precision required. Atomic clocks are more precise time keeping devices on earth. Have been invented fifty years ago, when it was discovered that the oscillations of atoms in certain energy levels, in particular, has never changed and vibrates at high frequency (more than 9 billion times per second for cesium).

Modern atomic clocks are so accurate that will not lose more than one second in 100 million years, but who on earth would need such precision? Atomic clocks are the basis for many applications and technologies and have contributed to our understanding of the physical universe.

Atomic clocks satellite systems, GPS navigation we use in our cars. The signals from atomic clocks on board satellites, which are used to triangulate an accurate position. E 'ca be made solely because of the very precise time signals. The inaccuracy of a second GPS clock could see demand of about 100,000 km in distance light can travel at that time.

Atomic clocks are also used as a method to test theories of Einstein and others. Using atomic clocks, we can accurately measure the severity and how it affects the weather. Modern clocks are so accurate that scientists can also measure the difference in gravity (and thus the time) in every inch above the soil surface next AOS. They can also be used to measure the slow process in motion, such as continental drift or slight changes in ODS rotation of the Earth.

Other applications where precision is essential to also rely on atomic clocks as the air traffic control, where the precise nature can follow a safe air traffic. Systems such as traffic lights are more and more time with servers connected to an atomic clock to ensure Synchonization perfect. Internet The Internet is based on atomic clocks, especially when it is used for time sensitive transactions such as banking, trading in stocks and shares and also book tickets online. Specified time, applications like this I laugh, AOT is possible that too many errors can occur in such a way that the seats of a double booking, selling shares were first purchased.

Networks of computers to synchronize the clock with Network Time Server. Often, these devices use the NTP protocol and receive the atomic clock time is the GPS or the radio. NTP time server to check and adjust all the clocks on the devices on a network to match the atomic clock time.
