FIELD: physics, clock.
SUBSTANCE: invention is designed for application in isolated systems of universal time, in which precise time signals are transmitted for synchronisation of territorially distanced clocks. Invention is aimed at improvement of readings accuracy and synchronisation of distanced clocks. This result is provided by the fact that system of clocks synchronisation by wire radio channel contains master clock, group of distanced clocks. According to invention master clock consists of serially connected program unit of clocks correction and unit of time storage, outlet of which is connected to group of distanced clocks via network interface. Besides device for decoding of precise time signal is additionally introduced, which consists of serially connected unit of radio signal conversion, signal receiver, program unit of signal separation and communication device, outlet of which via communication interface is connected to program unit of clock correction, the first inlet of radio signal conversion unit is connected to radio channel by means of galvanic isolation, and the second inlet - to source of reference voltage, the second inlet of program unit of signal separation is connected to source of clock rate.
EFFECT: improved accuracy of readings and synchronisation of distanced clocks.
