In this research, we will develop a space-time information platform by networking ¡°optical lattice clocks¡±, which improved the uncertainty of the atomic clocks used in GNSS (Global Navigation Satellite System) by three orders of magnitude. This platform will benefit future high-capacity network systems, navigation, and other services.
