| Abstract: | Since after 1950s, atomic frequency standards appeared, greatly promoted the develop- ment of science ＆ technology, along with the development of atomic frequency standards, high-precision time-frequency information in space science ＆technology played an important role. This article describes the application prospects of the high-precision time- frequency in space science, fundamental physics and satellite navigation technology, and preliminary discusses high-precision time-frequency of ongoing pro- grams, carrying out scientific and applied research, and Pulsar time in space science ＆ technology in for- eign countries. Finally, it takes out some recommendations for high-precision time-frequency in space scientific＆ technological research. |
