The time service server of Beidou refers to the time server based on the Beidou satellite signal. At present, there are many kinds of function classifications of time server. According to market demand or receiving the limitation of satellite environment, it can be divided into time server for receiving GPS satellite information, time server for receiving Beidou satellite information, receiving GPS Beidou satellite time information time server, and receiving time server of GPS Beidou GLONASS satellite information.

The above time servers are time servers that receive satellite signals as the time base. It is also advantageous to receive a variety of satellite signal time servers in the actual application process. For example, when a satellite loses its signal, other satellites can also provide satellite time information. This multi satellite time server is good, but in some domestic industries. In secret work, people are still used to the Beidou time server. The Beidou time server receives the satellite signals of its own country, and it can not be restricted in national defense secrecy and time security.

With the development of science and technology, the Beidou satellite has also developed from the Beidou generation to the two generation, and has improved a lot in terms of time scope and positioning function. I believe that the Beidou satellite will continue to improve and achieve better results, so as to meet the needs and development of all walks of life.At present, the time server based on satellite signal is used for time service through the way of NTP network signal output, but there are also some times that the server receives time by serial port, B code, PTP and so on. These timing methods are also chosen according to the environment of the user or the type of receiving equipment, but in many time service environments, the network transmission time information is used. Still more.

The Beidou timing server receives the Beidou satellite signal and performs the time service with the output of the NTP network. The SYN2136 Beidou NTP network time server produced by our company not only supports GPS satellite information, but also supports Beidou satellite information, which can also support GPS Beidou mixed signal, timing the network signal, and each network port is independent of the LAN. The time server can be used in different scenarios. The timing principle of the device SYN2136 Beidou NTP network time server receives the GPS Beidou satellite time information via the antenna, and transfers it to the time server. The time server receives the satellite signal to synchronize the machine, then transfers the NT network output to the SYN6109 NTP network sub clock and other network terminal devices, and ensures the synchronization of all devices and satellite time.

With the rapid development of science and technology and the rapid development of all walks of life, Beidou NTP network time server has been constantly updated. The server has increased the functions of SNMP network management, firewall, watchdog, NTP network operation status monitoring, and other functions to meet the needs of all walks of life. In addition, the time server is built with high precision temperature compensation crystal oscillator. When the satellite signal is lost, it can also achieve long time and high precision time keeping function, and can provide accurate time information and pulse output time effectively.
