Under the development of science and technology, GPS Beidou NTP time server has also been widely used, such as industry, scientific research, aerospace, public places and other fields, GPS Beidou NTP time server is used. The time server takes the time of satellite as the benchmark to provide accurate timing, replacing the shortcomings of single timekeeping and large time errors of traditional timepieces.

GPS Beidou NTP time server refers to the time server that receives the GPS Beidou satellite signal and carries out the timing through the NTP network protocol. SYN2136 Beidou NTP network time server configuring satellite signal receiver, can receive single Beidou or single GPS satellite and GPS Beidou mixed signal, and use network signal timing, each network port is independent LAN not interfere with each other, time server can give a variety of different time system for time service.

The principle of time service: SYN2136 Beidou NTP network time server receives the GPS Beidou satellite time information by satellite antenna, and transmits it to the time server through coaxial cable. The time server receives the satellite signal through the internal receiver to synchronize the machine, then transfers the SYN6132 pointer pointer and other network terminal devices through the NTP network protocol to make the terminal equipment and time. Time synchronization between servers. The time server can also send time to the serial port terminal through serial port information, and test the time server through 1PPS synchronization pulse signal.

The principle of punctuality: SYN2136 Beidou NTP network time server receives time from the terminal equipment by receiving satellite signals. When the time server loses the satellite signal, it can not guarantee the time accuracy, which requires the time server to keep the time function. The time server is built with high precision temperature compensation crystal oscillator. When the satellite is out of lock, it can also achieve long time and high precision time keeping function, and provide accurate time information and pulse output time. It is a special timing instrument for establishing time scale and realizing time unification. Time server can also choose constant temperature crystal oscillator, rubidium atomic clock, tame constant temperature crystal oscillator module, tame rubidium clock module and other modules with high punctuality.

Product features: SYN2136 Beidou NTP network time server has NTP network output, 1PPS synchronization pulse signal, 1 serial port timing, network timing accuracy 0.5-10ms, NTP request volume greater than 4000 times / sec, time server can give 10000 devices time, and support a variety of operation system and a variety of NTP time service agreement, support password verification and firewall protection, SYN-flood protection and soft Hardware watchdog function, QoS traffic monitoring and device selection in Chinese and English, real-time monitoring of NTP running status and network diagnosis, encrypted communication and heartbeat detection redundancy backup, remote maintenance operation and SNMP network management functions, but also through the WiFi wireless management function to use mobile phones to manage NTP network time server.
