Global Positioning System (GPS)
Telecommunications involves the transmission of information from a sender to a receiver through an electromagnetic or light-wave medium. Data transfer is an important feature in telecommunications operations and it needs accurate timing. In a telecommunications network, switches directing digital signals have to synchronize with each other, so that the data does not become corrupt or lost. Timely data transfer and synchronization are guaranteed by atomic clocks, which are the best timekeepers. Thus, atomic clock timing is a fundamental component of national and international telecommunications networks. Atomic clock stability is crucial to the smooth functioning of a mobile network. Without accurate time, there can be no proper functioning of the Internet, mobile phones, and e-mails. The distribution of voice and data around the world via a telecommunications network is very much dependent on accurate timing. Voice and data units are time-stamped to enable the transmitted elements...
