【摘要】：高精度时间频率的产生和超高精度时频信号的传递是现代物理学、天文学和计量科学的基础。空间原子钟组计划(Atomic Clock Ensemble in Space,ACES)是由欧洲空间局实施的基于国际空间站(International Space Station,ISS)微重力环境下的新型空间微波原子钟实验验证项目。概要介绍ACES项目基本情况,重点介绍ACES项目的主要科学和技术目标,围绕科学目标而形成的ACES组成结构,并梳理涉及的关键技术,特别介绍了ACES将应用的超高精度时频传递技术,为我国自主研究并实现相关空间时间频率系统及其应用提供参考。最后简述了我国正在建设的空间站时频系统主要情况和实施计划。
[Abstract]:The generation of high-precision time-frequency and the transmission of ultra-high precision time-frequency signals are modern physics. Fundamentals of astronomy and metrology. Atomic Clock Ensemble in space atomic clock group project, a new type of space microwave atomic clock experimental validation project under microgravity environment based on the international Space station station ISS, carried out by the European space agency-outline. The basic situation of ACES project is introduced. This paper mainly introduces the main scientific and technical objectives of the ACES project, the structure of the ACES formed around the scientific objectives, and combs the key technologies involved, especially introduces the ultra-high precision time-frequency transmission technology to be applied by ACES. This paper provides a reference for the independent research and implementation of space-time-frequency system and its application in China. Finally, the main situation and implementation plan of the space station time-frequency system under construction in China are briefly described.
