The GPS network time server takes the GPS satellite signal as the time benchmark and outputs the NTP network time information. NTP is the network time protocol which is used to synchronize the computer. It can transmit the standard time data packets in the network by broadcasting the hairstyle, and the equipment needs time synchronization in the network to set up the operation system correspondingly, so that the time is automatically synchronized to the NTP time service. To achieve time synchronization in the whole network.

The GPS network time server takes GPS satellite as the time benchmark and outputs UTC international standard time to provide time service. GPS network time server is composed of external signal receiving unit, signal processing unit, output time unit and timing device. The GPS network time server receives the time signal to decode and process, and converts the UTC international standard time to the local standard time, that is, time, month, day, time, minute and seconds and other time information, and converts it into a recognizable signal of the terminal equipment, thereby realizing the time and time synchronization function of the user equipment.

GPS network time server mainly uses NTP network time information to give time, but it also adds serial port time information, IRIG-B code time information, PTP time information, pulse time information and other timing methods according to user needs.

At present, the GPS network time server produced by Xi'an synchronization has many models for users to choose. For example, the SYN2104 NTP network time server, the built-in satellite receiver timing accuracy is 30ns, the GPS network time server can take GPS satellite signal as the time benchmark, and output the network, serial port, second pulse and other time signals to the terminal equipment to give time. The network timing accuracy is 1-10ms, and the time error between multiple clients can be less than 2ms. The timing accuracy of Wan is about 50ms. The time throughput of SYN2104 NTP network time server can reach 4000 times /s. Throughput is how many devices can be supported per second and requests time to the server. Therefore, the NTP network time server can support tens of thousands of devices to give time.

The SYN2104NTP network time server outputs 4 NTP network timing, and it does not interfere with the independent network port. The GPS network time server has many functions, such as password authentication, firewall, SYN-flood defense, encrypted communication, heartbeat detection, SNMP network management, WiFi wireless management, redundant backup and real-time monitoring. The SYN2102 NTP network time server has built-in high precision temperature compensation crystal oscillator, which can be punctual when the satellite is out of lock.

After receiving the satellite signal, the GPS network time server transfers the network output to the terminal device to synchronize the device time in the LAN. This timing method can be used in many industries, and can provide precise standard, safe, reliable and multi-functional NTP time service.
