Recently, our company has producedBeidou synchronous clock successfully put into operation at Huashu Digital TV Media Group Co., Ltd

Beidou synchronous clock(GPSNetwork synchronizer,GPSUnified timing device,Beidou Satellite Timing Server)withGPSCoordinated Universal Time (UTC) transmitted by the Beidou Satellite System（UTC）As a time source, the time signal passes throughCPUUnit processing into common timing signals (serial port, pulse, etc.)BCodeNTPNetwork portPTP）Output provides a unified and accurate clock signal source for various automation devices, and can be directly connected to computer networks as time servers, enabling large-scale, cross regional computers and network systems to obtain accurate synchronization time.

Beidou synchronous clockThe device adoptsGPSAs a time standard, the Beidou receiver accurately calculates leap years and leap seconds, and has the characteristics of high accuracy, high reliability, and all-weather. It can be widely used in industries such as aviation, transportation, power, chemical, and telecommunications.
