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.
La Crosse Technology introduced the radio-controlled clock, commonly (but incorrectly) called an "atomic clock" after the extremely accurate timepiece behind the radio signal it uses as a reference, into the United States commercial market in 1991. [3] [4] In 2004, the company was awarded a license to sell The Weather Channel branded weather ...
A valve-regulated lead-acid battery is a battery type that is popular in telecommunications network environments as a reliable backup power source. VRLA batteries are used in the outside plant at locations such as Controlled Environmental Vaults (CEVs), Electronic Equipment Enclosures (EEEs), and huts, and in uncontrolled structures such as ...
WWVB is a longwave time signal radio station near Fort Collins, Colorado and is operated by the National Institute of Standards and Technology (NIST). [1] Most radio-controlled clocks in North America [2] use WWVB's transmissions to set the correct time.
BPC transmits a time signal on 68.5 kHz, which can be used for synchronizing radio controlled clocks. The transmission site is situated near Shangqiu , Henan Province [ 1 ] at 34°27′25″N 115°50′13″E / 34.457°N 115.837°E / 34.457; 115
This is sufficient for radio controlled low cost consumer grade clocks and watches using standard-quality quartz clocks for timekeeping between daily DCF77 synchronization attempts, as they will be most accurate immediately after a successful synchronization and will become less accurate from that point forward until the next synchronization.
