Abstract

In this paper, the connotation of space-time reference and its relationship with space activities are described comprehensively. Time system, celestial reference frame, planetary ephemeris and pulsar timing are outlined. The gap between China and abroad development on space-time reference and its causes are analyzed. At the end, some suggestions for future development in China are proposed.
