Mains gps / Beidou Satellite Synchronization System Dual

Mains GPS / Beidou dual system synchronous satellite clock system, Beidou and GPS antenna for receiving satellite signals, the satellite signal through the power splitter into the way the GPS signal and one Compass signals, GPS signals obtained Beidou signal as a reference source signal, and a reference signal source and the IRIG-B signal fed to the synchronous clock device, a timing device synchronized clock module switching reference signal source selection, and the local oscillation closed loop control section, the final output clock signal power. The present invention adopts the above technical solution, Beidou passive timing technology, high-precision phase measurement techniques, multiple clock lossless switching technology, to complete the implementation of the Compass, GPS satellite system as a dual clock synchronization time reference synchronizing clock to meet technical specifications grid parameter FBI clock technical requirements. The invention solves the technical status of the existing domestic network time synchronization system over-reliance on the GPS system, improve the safety and reliability of the network time synchronization system.
