Abstract: Since after 1950s, atomic frequency standards appeared, greatly promoted the development 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 programs, carrying out scientific and applied research, and Pulsar time in space science & technology in foreign countries. Finally, it takes out some recommendations for high-precision time-frequency in space scientific& technological research.
Key words: Time-frequency, Space-science, Fundamental physics, +Pulsar
