Abstract
Traditional remote sensing systems struggle to meet the globalized and high-timeliness demands for earth observation,driv-ing a profound transformation of the earth observation system toward large-scale heterogeneous constellations.This study provides a systematic review of recent advances in this field,at the architectural level,it focuses on key technologies such as heterogeneous collab-orative design,onboard intelligent processing,and dynamic resource scheduling;at the application level,it examines emerging para-digms including the integration of communication,navigation,and remote sensing,as well as real-time remote sensing,along with asso-ciated industrial ecosystem shifts;it also analyzes core challenges in system governance,collaborative control,processing efficiency,re-source optimization,and ecosystem maturity.Looking forward,the technology is expected to evolve toward cognition,integrated,and adaptive capabilities,serving as critical space-based infrastructure for sustainable development.关键词
