  • GPS NTP Network Time Server
    The NTP (Network Time Protocol) time server is based on signals from global positioning satellites (GPS and BDS) as the reference source. The time reference in the GPS/BDS satellite signal is synchronized with Coordinated Universal Time (UTC), and the long-term frequency stability reaches the level of 10-13 of cesium atomic clocks, equivalent to slowing down by only one second every 300,000 years.
