Introduction to GPS time
GPS is short for Global Positioning System . GPS positioning satellite positioning, navigation systems worldwide . GPS has the all-weather, high precision and automatic measurement features have been incorporated into the national economic construction, national defense construction in various fields and social development. In the field of timing device, GPS time service is the acquisition time of a GPS satellite signal, and the signal through the switch device time information required to transmit the automation system .
GPS timing is used in the field timing device, also known as standard time server, serial time server, NTP network time server system, IRIG-B code time system, when the system equipment, IEEE 1588V2 clock, CPCIe timing card, frequency standard and the like, as long as the settling time is GPS timing signals are referred to a reference GPS time unit.
With technological development, all walks of life continue to progress, the field of GPS time applications are increasingly being used, which SYN2102 type NTP network time server, GPS is receiving input signals, output signals for the network output, 1PPS pulse, serial port time service and other functions, and it is widely used in hospitals, schools, government, stadiums, exhibition halls, research institutes, factories and so on. SYN2102 type is two when the network port corresponding to two timing NTP time service server, a client may be increased NTP network capacity can be backed up to each other. The clock network server with password authentication, firewall protection, the SYN-Flood defenses, encrypted communication, heartbeat detection, redundancy, remote maintenance and real-time monitoring and other functions, multiple time servers or multiple network ports can be set to the same IP, mutually redundant backup. SYN2102 type NTP network time server works as follows:
SYN2102型NTP网络时间服务器通过GPS卫星授时，以GPS卫星为标准时间信号，保证了时间的标准信号源，并通过2路物理隔离的NTP网络授时接口传递给需要时间信息的设备，设备支持多种操作系统的时间同步，支持多种协议。在安全性能上，提供防火墙保护，启用SYN-flood防御，极大地提高内部网络的安全性，降低风险；虽然SYN2102型接收GPS标准的时间信号源，但是要保证准确时间授时，设备还要满足时间同步和网络输出时间信号的要求，SYN2102型利用卫星时间信号实现全球范围时钟同步，通过网络的NTP协议与时间源进行时间校准，使局域网设备时间保持统一精准。设备内置时钟源可选温补晶振、恒温晶振、铷原子钟和驯服模块等，在没有电源的情况下对时间进行守时，保证时间的使用。
