Abstract

Taking space-time datum of Global Navigation Satellite Systems as a clue, this paper starts from the basic principle of GNSS (Global Navigation Satellite Systems) and it's technical realization including space-time relation, orbit and distance measurement, precise timing and time synchronization, expounds the fundamental contribution of Chinese Academy of Sciences (CAS) in precisely measuring and basic supporting for space-time datum which is the most indispensable for BDS (China's GNSS).
