What Is a SkyScan Atomic Clock?

SkyScan atomic clocks convey the most accurate time and date possible according to the U.S. atomic clock, the official national timepiece. SkyScan atomic clocks automatically calibrate daily in response to low frequency radio transmissions emitted by the U.S. atomic clock.

Located in Fort Collins, Colorado, the National Institute of Standards and Technology operates the official U.S. atomic clock. An internal receiver in the SkyScan atomic clock receives and decodes NIST radio signals. The signal is refreshed each day, ensuring the clock's accuracy to a fraction of a second. SkyScan atomic clocks are available for purchase at authorized retailers nationwide, including Sam's Club, Costco and Target.
