The GPS network time server is a high -tech product when computers, control devices, etc. in the automation system. The network time server device obtains the standard time signal from the GPS satellite. In the system, the device that requires time information (computer, protection device, fault recording, event order recording device, security automatic device, long -motion RTU) can achieve the time synchronization of the entire system.

　　Simple operations and other characteristics, fully automatic and intelligent operation, exemption and maintenance, suitable for unattended and widely used in various fields such as power, finance, communication, transportation, radio and television, petrochemical, metallurgy, national defense, education, IT, public service facilities.

　　With the rapid development of computer and network communication technology, the era of digitalization and networking of automated systems in various industries has arrived. Computer and network devices provide better platforms for data exchange, analysis and application between control and information systems, so that the accuracy of various real -time and historical data timestamps also puts forward higher requirements. However, the network These devices have their own time, and the time of accumulation of the entire system is confusing, resulting in normal data statistical analysis business cannot be carried out normally. At this time, the entire network time needs to be synchronized.
