Description
The 6th generation of NBS Atomic Frequency Standards, NBS-6, was at the time of its unveiling the most accurate atomic clock NBS had developed to date. This instrument was the heart of the NBS Atomic Clock System, which also included other atomic frequency standards and clocks, a computer, and instrumentation used to inter-compare the various components. An atomic clock is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS.
