The Beidou time server refers to the time server for receiving Beidou satellite signals. With the development of science and technology, the application of satellite positioning and navigation technology is becoming more and more extensive. This kind of time server with satellite time information as the time source and the application of network information timing equipment are also increasing. At present, according to the usage environment and market demand, the time service server has a time server that can receive GPS, Beidou and GLONASS satellites. Beidou is a satellite made in China, and its positioning and navigation technology has also been upgraded to the international level, and its use is stable and reliable.

The Beidou school has a built-in high precision receiver, its accuracy is less than 30ns, and the sensitivity of timing antenna is less than -160dbm. The Beidou school server receives the Beidou satellite time signal, and uses NTP network output, 1PPS second pulse output, serial port output, and other time signals to give the equipment time. The timing accuracy of the network is 0.5-10 milliseconds, and the 1PPS second pulse timing accuracy is less than 30ns. Besides the above time service, there are other times that the server gives time to the equipment through B code, IEEE1588 and so on.The timing of the timing depends on the actual application environment. The Beidou school used in schools, hospitals, factories, power plants, venues, scientific research institutions, transportation facilities and other industries, the server still uses NTP network signals to provide time service. The NTP network allows time to facilitate the transmission of time through only the network cable, and NTP network signals can be carried out through switches. The shunting can provide tens of thousands of devices for time service, and the Beidou school server is timing accurately based on the Beidou satellite signal time benchmark.

The Beidou school server changed the past single time service mode. Its appearance enabled people to make better use of time, and at the same time saved a lot of manpower and material resources. The Beidou school server can monitor the time information of each device and ensure the time security of the LAN. At present, the SYN2136 Beidou NTP network time server produced by our company supports three modes: single Beidou satellite signal, single GPS satellite signal and GPS Beidou satellite mixing mode. The network signal output is real-time to the equipment, and each network port is independent of the LAN. The device has firewall, SYN-flood defense, hardware and software watchdog, QoS function, monitoring time and heart. Such functions as hop detection, encrypted communication, SNMP network management, remote maintenance, redundant backup and so on. SYN2136 Beidou NTP network time server built-in temperature compensation crystal oscillator can be punctual for equipment.

The working principle of the Beidou school server is to transmit the satellite signal to the time server after receiving the satellite signal. The time server converts the satellite time information to the terminal equipment through the network output, and makes all the equipment time in the LAN point point to the server of the North dodge school.
