【摘要】：高精度時(shí)間頻率的產(chǎn)生和超高精度時(shí)頻信號(hào)的傳遞是現(xiàn)代物理學(xué)、天文學(xué)和計(jì)量科學(xué)的基礎(chǔ)�？臻g原子鐘組計(jì)劃(Atomic Clock Ensemble in Space,ACES)是由歐洲空間局實(shí)施的基于國(guó)際空間站(International Space Station,ISS)微重力環(huán)境下的新型空間微波原子鐘實(shí)驗(yàn)驗(yàn)證項(xiàng)目。概要介紹ACES項(xiàng)目基本情況,重點(diǎn)介紹ACES項(xiàng)目的主要科學(xué)和技術(shù)目標(biāo),圍繞科學(xué)目標(biāo)而形成的ACES組成結(jié)構(gòu),并梳理涉及的關(guān)鍵技術(shù),特別介紹了ACES將應(yīng)用的超高精度時(shí)頻傳遞技術(shù),為我國(guó)自主研究并實(shí)現(xiàn)相關(guān)空間時(shí)間頻率系統(tǒng)及其應(yīng)用提供參考。最后簡(jiǎn)述了我國(guó)正在建設(shè)的空間站時(shí)頻系統(tǒng)主要情況和實(shí)施計(jì)劃。
[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.
