The GPS satellite positioning system can be applied to many fields, such as military, national defense, communications, time service, etc. The application of GPS satellite positioning system in transmitting time is transmitting satellite signals to equipment and giving time. GPS network time server is a time server for receiving GPS satellite signals. It can convert satellite time signals into time information such as network, serial port and second pulse, and can provide users with corresponding time information. The GPS network time server mainly outputs the network time signal. It can provide time service in many environments, and the time service is accurate and easy to use, which changes the traditional timekeeping mode.

The function and type of time server are all different. According to the output signal, it can be divided into serial port time server, NTP network time server and CDMA time server. According to the satellite signal source, it is divided into GPS time server, Beidou time server, GPS Beidou time server and so on. The functions of general time servers vary from price to price. For example, some time servers require multiple network ports output, B code output and serial port output. For example, some time servers will also affect prices in different aspects such as network port, NTP request volume, working temperature, storage temperature, power supply, operation system, crystal oscillator and so on.

With the continuous improvement of technology, the function of NTP network time server is also constantly improving. Its function has been oriented to diversified development, and can meet the needs of most users and use environment, and the equipment has high cost performance, convenient timing and precise time. The SYN2101 NTP network time server takes the GPS satellite signal as the time source and uses the Linux operating system. It can output network information, serial port signal, second pulse signal and other time information, and the built-in temperature compensated crystal oscillator can also keep the time on the device without satellite signal. The product also adds firewall protection, heartbeat detection, redundant backup, software and hardware watchdog design and other functions to truly meet various user needs.

GPS network time server can provide accurate, standard, safe and reliable NTP time service to network devices, and GPS network time server can provide tens of thousands of devices to time service. The timing principle is as follows: SYN2101 NTP network time server receives the standard time signal of GPS satellite, and transmits the time information through network output, serial port output and pulse output to the computer. SYN6109 type NTP network sub clock, electrical meter, alarm equipment, monitoring equipment, weak electronic system, and other equipment that needs time service, so that the time needed for equipment is synchronized with the satellite standard time source.

The GPS network time server has solved the demand for time in many fields, facilitated people's demand for time application, and saved many costs. The GPS network time server can provide high precision standard time signals for communications, hotels, schools, hospitals, venues, government, factories, broadcasting and television, security monitoring, industrial control and so on.
