Abstract:The current status and development trends of high-resolution satellite-based imaging observation systems based on optics, radar, and hyperspectral payloads are analyzed, and the planning and introduction status of typical high-resolution earth observation systems abroad are introduced. The research shows that with the rapid development and application of key technologies such as micro-nano satellites, high-performance payloads, and artificial intelligence, the new-generation ground observation system planned abroad is mainly based on intelligent small satellite clusters. Satellite platform research focuses on high-performance micro-nano satellites, software-defined satellites, small satellite groups. Based on improving the time, space, and spectral resolution of the load, integration, intelligence, and miniaturization is the future development trends for payload side research. The study investigates the latest researches of foreign countries and agencies, aiming at providing a reference for the new generation of high-resolution earth observation system in China.
