The invention discloses a Beidou satellite timing system and method. By the adoption of the Beidou satellite timing system and method, Beidou satellite time signals can be read and stably displayed in real time through an LED dot-matrix display screen, and network time synchronization is conducted on network devices in a wireless network. According to the Beidou satellite timing system and method, a satellite navigation message is received through a Beidou navigation module and a GPS navigation module, whether locating conducted by the Beidou navigation module succeeds or not is judged through a field-programmable gate array module, and universal time is extracted, converted and displayed by the LED dot-matrix display screen; a micro control unit judges whether a network timing requirement or a dot-matrix brightness adjustment request is received or not; if yes, time information is added to a network time protocol transmitted in the wireless network for network time synchronization or brightness is adjusted by adjusting the gate time of a dot matrix, and if not, judgment continues. The Beidou satellite timing system and method achieve LED dot-matrix display of time service and the network time synchronization function and are wide in application range, and the stability of the system is high.
