In recent years, China has made significant progress in the field of satellite computing and is building an integrated space-based intelligent infrastructure that unifies sensing and computing in space. These advancements are first reflected in the rapid growth of the number of satellites. Secondly, multi-satellite constellations enable on-orbit edge computing, inter-satellite collaboration, and AI inference, driving satellite systems to evolve from data acquisition to intelligent processing. China possesses both land-based and sea-based launch platforms, demonstrating a steadily maturing all-domain space launch capability. Satellite intelligence has promoted technological progress in many application areas, such as ecological environment management and biodiversity conservation. In this talk some representative cases are to be introduced.
