With the continuous improvement and development of science and technology, all walks of life are also developing rapidly and changing, and all industries have put forward higher requirements for the accuracy and portability of time service equipment, so ordinary time service equipment can not meet the needs of various industries. Until the time synchronization server appears to meet the needs of different industries, time synchronization server can provide accurate, standard, safe, reliable and multi-functional NTP time service for time service devices.

The time synchronization server can receive GPS, Beidou, GLONASS and other satellite signals, and can clock and other devices to give time. The time synchronization server is a high-tech intelligent product, it can support a variety of time service protocols, such as NTP network protocol, IEEE 1588PTP protocol, serial port protocol, IRIG-B code protocol, and use NTP network output, serial port output, second pulse output, B code output and other signal timing, time synchronization server time convenient and efficient. At present, the time synchronization server can be divided into NTP network time server, serial port time server and PTP clock according to the output timing signal. It is divided into CDMA time server, GPS time server, GPS Beidou time server and PTP clock according to the received signal.

Time synchronization server applications can be applied to hospitals, schools, government, sports venues, exhibition halls, research institutes, factories and other fields. SYN2136 Beidou NTP network time server configuration satellite signal receiver timing accuracy is less than 30ns, can receive single Beidou or single GPS satellite and GPS Beidou mixed signal, and output NTP network, 1PPS pulse, serial port, and other timing signals, in which network timing accuracy 0.5-10ms, second pulse synchronization error is less than 30ns. And each network port is independent of the LAN. It can also set up multiple network ports for the same IP, supporting multiple operating systems and time protocols. The time synchronization server has the functions of password verification, firewall protection, SYN-flood defense, encrypted communication, heartbeat detection, time monitoring, remote maintenance, SNMP network management, WiFi wireless management, redundant backup, real-time monitoring and other functions. The SYN2136 Beidou NTP network time server is equipped with temperature compensation crystal oscillator, selectable constant temperature crystal oscillator, rubidium atomic clock and tame module. It also has time keeping function. When the satellite is out of lock, the device can be punctual and ensure the time is accurate.

The time synchronization server's time service principle is to receive satellite signals through the timing antenna, and then transmit it to the SYN2136 Beidou NTP network time server by coaxial cable. The time synchronization server outputs the network time signal through internal conversion, then transfers the signal to the switch. After receiving the signal, the switch sends it to the SYN6109 mode. NTP network sub clock, computer, monitoring equipment, weak electronic system and other terminal equipment, and ensure equipment and satellite time unification and time synchronization between devices.
