The transportable hydrogen quantum clock, developed by VNIIFTRI, is based on a small-sized active hydrogen generator with a storage vessel made of single-crystal leucosapphire.

Small-sized, cost-effective, has high metrological characteristics, can function in harsh operating conditions, transportation by all means of transport in working condition is possible.

measuring the difference of time scales of spatially separated standards of time located at a distance of up to 1000 km with an error of not more than 2 ns;

measuring the frequency of the reference signals of remote standards, as well as determining the instability parameters of their frequencies and spectral characteristics of the signals;

storage of a time scale and a source of reference precision signal at mobile and stationary objects.
