  2. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    Atomic clocks and their usage in GPS, by Bill Hammack. 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

  3. Speaking clock - Wikipedia

    en.wikipedia.org/wiki/Speaking_clock

    A speaking clock or talking clock is a live or recorded human voice service, usually accessed by telephone, that gives the correct time. The first telephone speaking clock service was introduced in France, in association with the Paris Observatory, on 14 February 1933. [1] The format of the service is similar to that of radio time signal services.

  4. Talking clock - Wikipedia

    en.wikipedia.org/wiki/Talking_clock

    A talking clock (also called a speaking clock and an auditory clock) is a timekeeping device that presents the time as sounds. It may present the time solely as sounds, such as a phone-based time service (see " Speaking clock ") or a clock for the visually impaired, or may have a sound feature in addition to an analog or digital face.

  5. 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. Time and frequency transfer - Wikipedia

    en.wikipedia.org/wiki/Time_and_frequency_transfer

    In a two-way time transfer system, the two peers will both transmit and receive each other's messages, thus performing two one-way time transfers to determine the difference between the remote clock and the local clock. [4]: 118 The sum of these time differences is the round-trip delay between the two nodes. It is often assumed that this delay ...

  8. International Atomic Time - Wikipedia

    en.wikipedia.org/wiki/International_Atomic_Time

    TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3] The majority of the clocks involved are caesium clocks; the International System of Units (SI) definition of the second is based on caesium. [6] The clocks are compared using GPS signals and two-way satellite time and frequency ...

  9. Nuclear clock - Wikipedia

    en.wikipedia.org/wiki/Nuclear_clock

    The expected performance of a single-ion nuclear clock was further investigated in 2012 by Corey Campbell et al. with the result that a systematic frequency uncertainty (accuracy) of the clock of 1.5 × 10 −19 could be achieved, which would be by about an order of magnitude better than the accuracy achieved by the best optical atomic clocks ...
