A
US government agency has developed
a new atomic clock that would neither gain nor
lose a second in about 300 million years, making it three times as accurate as
its predecessor.
The US Department of Commerce's National Institute of Standards
and Technology (NIST) launched the new atomic clock, called NIST-F2, to serve as a new US civilian
time and frequency standard, along with the current NIST-F1 standard.
NIST
scientists said according to the International Bureau of Weights and Measures
data, NIST-F2 is now the world's most
accurate time standard. Many everyday technologies, such as cellular
telephones, Global Positioning System (GPS) satellite receivers, and the
electric power grid, rely on the high accuracy of atomic clocks.
