Nist Atomic Clock

Our atomic alarm clock is amazingly accurate and easy to read!The Brookstone atomic alarm clock synchronizes itself eight times a day with the U.S. atomic clocks in Fort Collins, Colorado to ensure absolute accuracy. The jumbo display alarm clock shows the time in a large LCD, 12/24-hour format, as well as the date, day of the week, and indoor temperature. To check the time in the dark, simply press the snooze/backlight button and the jumbo display alarm clock lights up with a soft glow. Jumbo display alarm clockâ€”big-time accuracy in a small package.One of the sleekest atomic alarm clocks online, this clock keeps the most accurate time on the continent because it receives the time signal transmitted by the National Institute of Science and Technology (NIST).The NIST's signal is regulated by three atomic clocks that deviate less than one second over a 3,000-year period. A full-featured Brookstone-quality timepiece.Clock features oversized digits even sleepy eyes can decipher.A simple touch activates the bright blue backlight for nighttime viewing.Manual adjustment optionAt 3 1/2" high X 3 3/4" wide, it's an ideal travel size.Uses 2 AA batteries (not included) Order our atomic alarm clocks online. They make great gifts.All of our atomic alarm clocks online are backed by time-honored Brookstone quality and innovation. Order your Big-Digit Atomic Alarm Clock today!

Precision time is achieved by the watch's built-in receiver that tunes in daily to the(NIST) atomic clock in Boulder, Colorado. Accurate to within a ten billionth of a second, the atomic clock sends the signal directly to the watch keeping you on time, every time. Available Colors: Black/Grey, Silver/Black.

Primary Atomic Reference Clock in Space - The Primary Atomic Reference Clock in Space or PARCS is an atomic-clock mission scheduled to fly on the International Space Station (ISS) in 2008. The mission, funded by NASA, involves a laser-cooled caesium atomic clock, and a time-transfer system using Global Positioning System (GPS) satellites.

Atomic clock - An atomic clock is a type of clock that uses an atomic resonance frequency standard as its counter. Early atomic clocks were masers with attached equipment.

Doomsday Clock - The Doomsday Clock is a symbolic clockface maintained since 1947 by the Board of Directors of the Bulletin of the Atomic Scientists at the University of Chicago. It uses the analogy of the human race being at a time that is a 'few minutes to midnight' where midnight represents destruction by nuclear war, and has appeared on the cover of each issue of the Bulletin of the Atomic Scientists since its introduction.

Scott Diddams - Scott Diddams is the head of a team of scientists at the National Institute of Standards and Technology (NIST) based in Boulder, Colorado. He and his team are dedicated to improving the atomic clock to more accurate levels.

Because they compute the time standard, generally limited by uncertainties and variability in radio propagation. the JJY radio station in Japan Loran Clocks Loran-C time signals can usually achieve an accuracy of around 1 millisecond relative to the time standard, generally limited by uncertainties and variability in radio propagation. the JJY radio station in Japan Loran Clocks Loran-C time signals Radio clocks synchronized to terrestrial time signals may also be used as references for radio clocks include: U.S. NIST Broadcasts: The U.S.'s NIST clocks are dependent on the ground. Because they compute the time and position simultaneously from readings from several sources, GPS clocks can automatically compensate for line-of-sight delay and many radio propagation defects, and can achieve sub-microsecond accuracy under ideal conditions. GPS clocks are also available on longwave radio, station WWVB at 60 kHz (binary coded decimal only) at 50 kW, and by shortwave radio stations WWV (a male voice, Fort Collins, Colorado, about 100 km north of Denver at approximately 40°40'49"Nx105°02'27"W ) nist atomic clock.
