  3. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    The development of atomic clocks has led to many scientific and technological advances such as precise global and regional navigation satellite systems, and applications in the Internet, which depend critically on frequency and time standards. Atomic clocks are installed at sites of time signal radio transmitters. [113]

  4. Network Time Protocol - Wikipedia

    en.wikipedia.org/wiki/Network_Time_Protocol

    These are high-precision timekeeping devices such as atomic clocks, GNSS (including GPS) or other radio clocks, or a PTP-synchronized clock. [30] They generate a very accurate pulse per second signal that triggers an interrupt and timestamp on a connected computer. Stratum 0 devices are also known as reference clocks.

    Products included hydrogen masers, rubidium and cesium atomic standards, temperature and oven controlled crystal oscillators, miniature and chip scale atomic clocks, network time servers, network sync management systems, cable timekeeping solutions, telecom synchronization supply units (SSUs), and timing test sets.

  6. Radio clock - Wikipedia

    en.wikipedia.org/wiki/Radio_clock

    A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.

  7. Synchronization in telecommunications - Wikipedia

    en.wikipedia.org/wiki/Synchronization_in...

    Telecommunication networks rely on the use of highly accurate primary reference clocks which are distributed network-wide using synchronization links and synchronization supply units. Ideally, clocks in a telecommunications network are synchronous, controlled to run at identical rates, or at the same mean rate with a fixed relative phase ...

  9. Time signal - Wikipedia

    en.wikipedia.org/wiki/Time_signal

    There are many commercially available radio controlled clocks available to accurately indicate the local time, both for business and residential use. Computers often set their time from an Internet atomic clock source. Where this is not available, a locally connected GNSS receiver can precisely set the time using one of several software ...
