    18 cesium atomic clocks and 4 hydrogen maser clocks ... National Standard Time and Frequency Laboratory; ... European Space Agency; Düsseldorf, Germany;

  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. DCF77 - Wikipedia

    en.wikipedia.org/wiki/DCF77

    Of these atomic clocks, the CS2 atomic clock in Braunschweig provides the German national legal time standard, and can be used as a highly accurate frequency standard. [33] If there are deviations, the necessary corrections will be made via the telecontrol system. [34]

  5. Time from NPL (MSF) - Wikipedia

    en.wikipedia.org/wiki/Time_from_NPL_(MSF)

    The Time from NPL is a radio signal broadcast from the Anthorn Radio Station near Anthorn, Cumbria, which serves as the United Kingdom's national time reference. [1] The time signal is derived from three atomic clocks installed at the transmitter site, and is based on time standards maintained by the UK's National Physical Laboratory (NPL) in Teddington. [2]

  6. International Atomic Time - Wikipedia

    en.wikipedia.org/wiki/International_Atomic_Time

    International Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3]

  7. 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.

  8. Time in Europe - Wikipedia

    en.wikipedia.org/wiki/Time_in_Europe

    Pale colours: Standard time observed all year Dark colours: Summer time observed Europe spans seven primary time zones (from UTC−01:00 to UTC+05:00), excluding summer time offsets (five of them can be seen on the map, with one further-western zone containing the Azores, and one further-eastern zone spanning the Ural regions of Russia and European part of Kazakhstan).

  9. List of UTC timing centers - Wikipedia

    en.wikipedia.org/wiki/List_of_UTC_timing_centers

    List of UTC timing centers is a list of over 70 recognized maintainers of atomic clocks around the world from which UTC is calculated. [1] Below are links to some of the more notable time centers which contribute to the calculation of UTC.
