Hydrogen Masers

A Hydrogen Maser is an instrument that provides a timing signal to be used as the basis of reference for the control of other clocks within a network. The long-term accuracy of that signal is maintained at 1 x 10-11 or better. This primary reference source generates a timing signal completely autonomous of other references using passive or active hydrogen maser technology.
