The network time service server means the time server receives the satellite time information and outputs the NTP network output time information, and then sends it to the terminal equipment which needs time to realize the timing of the terminal equipment. NTP refers to the protocol that the network time protocol can synchronize the time of each computer in the network. It can provide time information to computers and other network devices.

The network timing server can receive the satellite signal CDMA as the time reference, and coordinate the UTC world as the standard time, and then convert it to Beijing time. The network time server can output NTP network, serial port, pulse, IRIG-B code, PTP and other time information. The timing accuracy of the network timing server is less than 30ns, the network timing accuracy is 0.5-10ms, the pulse time accuracy is less than 30ns, and the IRIG-B code timing accuracy is less than 200ns. The network time server has many kinds of time service interfaces, which can give different kinds of terminal devices time service. At the same time, it can also increase the number of output signals according to users' needs.

The network time service server has an identification mechanism to check whether the time information of the time is from the claimed time server and check the return path of the data to provide a protection mechanism against interference, thereby preventing the virus from malicious damage to the time server. The network time service server can give time to many computer devices, and the computer can choose the best path and source correction time. When the time server is not connected with the computer for a long time, the network time service server can still operate effectively.

At present, the SYN2131NTP network time server takes GPS satellite as the time benchmark, and then provides precise standard, safe and reliable time service to users with NTP network time signal and IRIG-B code time signal. NTP network time server has also added many functions, such as password authentication, WiFi management, SYN-flood defense, remote maintenance, QoS function, redundant backup, firewall, encrypted communication, heartbeat detection, real-time monitoring, SNMP network management function. The NTP network time server has built-in high precision temperature compensation crystal oscillator as the clock source, and can also choose constant temperature crystal oscillator, rubidium atomic clock, tame constant temperature crystal oscillator module and tame rubidium clock module according to the needs of users.

The working principle of the network timing server is that the GPS timing antenna receives the standard time signal of the satellite, and transfers the time information to the clock SYN2131 type NTP network time server. When the mother clock receives the satellite time signal, it needs to transform the output time signal and transmit it to the terminal equipment to ensure that all the equipment time in the LAN is synchronized with the master clock.

The network time server is easy to use, high precision, simple operation and good stability. It is used by various industries such as hospitals, schools, factories, broadcasting and television, finance, telecommunications, electricity, transportation and other fields.
