Characteristics of Beidou dual-mode clock timing

1Adopting multi synchronous source adaptive synchronization technology, the synchronization accuracy is better than ±30ns.

2Adopting a redundant structure.

dual supportGPSBeidou Hot Spare and DualIRIG-BHot standby and equipped with high-precision timekeeping clock. The standard time synchronous clock body can be connected simultaneouslyGPSBeidou and2roadIRIG-BOut of code synchronization signal, serving as backup for each other. The time scale signal expansion device can be connected simultaneously2roadIRIG-BOut of code synchronization signal, serving as backup for each other. Both the master clock and signal expansion device can use redundant devices to ensureGPSThe reliability and stability of the Beidou time synchronization system.

3Modular design, multiple output interfaces, flexible and convenient to use.

Capable of outputtingIRIG-B(AC)CodeIRIG-B(DC)Code, pulse, time message information,NTP/SNTPNetwork timing signal.

4DoubleCPUParallel Processing Time Message Output Technology

The time message output adopts dualCPUParallel processing technology, with a timing edge of seconds for message transmission and an error not exceeding+10Ms.

5High precision pulse output

The pulse output adopts a pulse high current generation circuit, which enables the photoelectric isolation contact point to output high-precision pulse signals with an error not greater than0.1Ms.
