Science China(Information Sciences) 2024年第9期67卷 338-339页

作者： Liang XU Jian JIAO Shiyao JIANG Ye WANG Qinyu ZHANG guangdong provincial Key Laboratory of Aerospace Communication and Networking Technology Harbin Institute of Technology (Shenzhen) Pengcheng Laboratory

The cohesive clustered satellite(CCS) concept integrates diverse satellite payloads from different orbits, such as communication, remote sensing, and navigation satellites, into mobile, geometrically stable clusters for efficient collaborative networking [1]. By aggregating, reconstructing, and orchestrating heterogeneous satellite resources, such as computation, communication, and storage [2], the CCS enables resource ultra-sharing and provides information-centric and goal-oriented intelligent on-demand services [3] for a range of emerging Earth observation and deep space exploration missions [4].
