Design of Time Synchronization System Based on GPS/BeiDou Satellite

The time synchronization system which uses the BeiDou and GPS as double clock source can receive GPS and the BeiDou satellite signal. The system built-in constant temperature crystal clock or rubidium clock utilizes the "BeiDou bidirectional synchronization method" technology and advanced control algorithm. The core control processor using STM32 chip with high performance, which can achieve multi-sources timing intelligent switching. The multi-sources timing not only enhanced the reliability of the system, but also enhance the security of the whole system. It can ensure the power system synchronization and also synchronize the whole network time in large area.
