Global position system (GPS) and Beidou satellite synchronous clock

The utility model discloses a global position system (GPS) and Beidou satellite synchronous clock which comprises a processor, a data display driver module, a FLASH memorizer, a synchronous dynamic random access memory (SDRAM), an Ethernet physical transceiver, a physical drive circuit, power-switching circuits, a GPS satellite receiving and decoding module and a Beidou satellite receiving and decoding module. The data display driver module, the FLASH memorizer, the SDRAM, the Ethernet physical transceiver, the physical drive circuit, a first power-switching circuit, the GPS satellite receiving and decoding module and the Beidou satellite receiving and decoding module are all in bidirectional connection with the processor. The GPS satellite receiving and decoding module and the Beidou satellite receiving and decoding module are both connected with a second power-switching circuit, and an output end of the data display driver module is connected with a digital display tube. The GPS and Beidou satellite synchronous clock has the advantages of having a low-power-consumption and self-heat-dissipation framework, a wide operating temperature range and a good electromagnetic interference resistance ability.
