Architecture design of the new-generation ecological and environmental satellite application system

Satellite remote sensing serves as the “thousand-mile eye” in the modern ecological and environmental monitoring system,its application system is the key guarantee for full exerting the effectiveness of satellite payloads. Currently, China,s capability in ecological and environmental satellites is continuously enhancing; however, the existing application systems can hardly support the data processing of multi-satellite and multi-payload missions,nor can they reach the increasing demand for operational applications in the future. This paper summarizes the current status and progress of domestic and foreign satellite application systems,and analyzes the new trends in ecological and environmental remote sensing monitoring. On this basis, in accordance with the principles of problem orientation, AI enpowerment, guided by scientific advancement, and qualitycontrollable, a multi-level architecture for the new-generation ecological and environmental satellite application system is designed. The core functions of the infrastructure layer, support layer, application layer, and user layer are defined. This architecture categorized three product levels:general,thematic,and application products and established two business processes:namely customized and routine processes. This system promotes standardized and intelligent transformation of ecological and environmental remote sensing monitoring,thereby providing strong support for high-level ecological and environmental protection.
