NTP time calibration server is a time server based on NTP network time protocol. NTP network time protocol is a protocol of synchronous computers, which enables computers to synchronize with time servers. It can provide millisecond high precision time information, prevent virus invasion, and better protect the security of time servers.

NTP time is to get UTC time from satellite, atomic clock and interconnection. UTC is also the international standard time. This ensures accurate time source. The NTP time calibration server receives the satellite time signal and outputs the time information in NTP network. In the process of giving time to the computer, the time server will choose the best time source to carry out the timing when the computer connection time server is more. If the computer does not connect the time server for a long time, the NTP time can still work. NTP can intercept the destruction of the virus and can effectively resist interference.

The NTP time calibration server can receive GPS and Beidou satellite timing and positioning signals as the time reference. GPS is a satellite of the United States, which can be used to locate and navigate the world. Beidou satellite is a satellite developed by ourselves. The performance of the Beidou satellite is constantly upgrading. The Beidou satellite can provide all kinds of users with high accuracy, high reliability location, navigation and time service all day long.
