中文摘要: 文章以全球卫星导航系统的时空基准为线索，从卫星导航系统原理及精准定位技术的实现出发，从时空关系、测轨测距、精准计时到时间同步等，综述了中国科学院为北斗卫星导航系统建设所依赖的时空基准技术所作的基础性支撑。
中文关键词: 全球卫星导航系统（GNSS） 时空基准 核心基础
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).
