摘　　要：近年来,随着互联网用户激增,SpaceX、OneWeb等创新型企业纷纷计划打造低轨互联网星座,引发全球低轨卫星互联网星座的发展热潮。因此,研究国内外低轨互联网星座的发展情况及当前面临的技术难题有着很重要的意义。基于此,介绍了国外具有代表性的3个低轨互联网星座计划(Starlink、OneWeb、Lightspeed)及国内星座的最新发展情况;根据低轨互联网星座的特点,着重分析了低轨互联网星座面临的五大技术挑战:星座相对运动演化预报、星座自主导航与定轨、星座构型重构的路径规划、星座自组织协同构型控制、星座通信与网络服务;根据当前低轨互联网星座的发展趋势,对中国在低轨互联网星座的发展给出了建议。In recent years,several innovative enterprises like SpaceX and OneWeb have initiated the LEO Internet constellations.Therefore,recognizing its importance to the internet usersis meaningful to review the state-ofthe-art technologies and the relevant challenges.In this review,three representative LEO Internet constellation plans(Starlink,OneWeb,Lightspeed)and the latest development in China are firstly introduced.Then,according to the characteristics of LEO Internet constellations,five major challenges of the LEO Internet constellations are analyzed,i.e.,prediction of relative motion evolution of constellation,autonomous navigation and orbiting of constellation,path planning for constellation configuration reconstruction,constellation self-organizing collaborative configuration control,constellation communication and network services.Finally,some suggestions are provided for the development of LEO Internet constellation in China.
