NIST-F1

NIST-F1 is a highly precise atomic clock developed by the National Institute of Standards and Technology. It measures time based on the vibrations of cesium atoms, which oscillate at a very consistent frequency. This clock serves as the official standard for the second in the United States, ensuring accurate synchronization for technologies like GPS, internet networks, and scientific research. Its precision helps maintain the global time scale, facilitating consistent and reliable timekeeping worldwide.
