The optical lattice clock, taken as a ridiculous idea in 2001, has come true and changed the game for building highly precise and stable atomic clocks. In this project, we will develop a space-time information platform by networking “optical lattice clocks”, which improve the uncertainty of atomic clocks used in GNSS (Global Navigation Satellite System) by three orders of magnitude. Such a platform will benefit future high-capacity network systems, navigation, and other services.
