Abstract
It is significant for science and military to establish a time and frequency system in space station to provide a more precise time and frequency standard through high accuracy time and frequency link for global civilian users.Firstly,the status and application of high accuracy time and frequency transfer technology for space station abroad is discussed.Then,based on the principle of two way time and frequency transfer(TWTFT),the idea of system design for China's space station microwave link(MWL) is proposed compared with the project of European Space Agency(ESA).Finally,two key technologies of high accuracy time and frequency transfer are analyzed,which are quite important for particular system design and realizing the picosecond level precision.关键词
