UNIVERSAL TIME SOURCE Russian patent published in 2024 - IPC G04G5/00 

FIELD: physics.

SUBSTANCE: invention relates to universal time (UT) systems for communication and automation systems of general and special purpose. Universal time source for communication and automation systems of general and special purpose comprises a receiving antenna which receives and amplifies a radio signal of satellite navigation systems (SNS) of GLONASS and GPS, receiving module of GLONASS and/or GPS SNS signals, which processes the received data, outputs time information to the microcontroller of the time signal unit, which generates and transmits PPS pulses, synchronized with the universal coordinated time UTS, microcontroller, which processes data coming from the receiving module, and generates and transmits to the node an interface serial time code according to NTP, SNTP and PTP time synchronization protocols (IEEE 1588-2008), quartz oscillator, performing microcontroller clocking, interface unit for connection of consumers, power supply unit and control module, wherein the receiving module of GLONASS and/or GPS SNS signals with the time signal unit is connected by means of corresponding optical modules by an optical one-way transmission line, which ensures delivery of GLONASS and/or GPS signals to a noise-protected area.

EFFECT: possibility to move the antenna and receiver of signals of global navigation systems outside the noise zone, which enables to avoid electromagnetic interference in the antenna and the receiver.
