Product Description. The GPS satellite clock in 19" enclosure is the base for all our GPS synchronized systems for 3U and more. The GPS-BGT consists of a power supply (input voltage determined by the customer, outputs as needed) and the GPS reference clock and can be customized with different modules and output drivers to fulfill your needs.. For example the following outputs are possible:
An atomic clock is a clock device that uses a hyperfine transition frequency in the microwave, or electron transition frequency in the 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 ...
