防灾可呼叫 卫星来“接单”

Core Viewpoint - The integration of commercial and civil remote sensing satellites in China has significantly enhanced the emergency response speed for disaster monitoring and mitigation, creating a unified platform for efficient data utilization [1][2]. Group 1: Satellite Resources and Capabilities - China currently has over 400 remote sensing satellites in orbit, covering optical, hyperspectral, infrared, and microwave types, enabling all-weather and all-time Earth observation [1]. - The National Space Administration has established a virtual satellite constellation and an emergency response mechanism for civil and commercial remote sensing satellites, leveraging the advantages of different satellite technologies [1]. Group 2: Emergency Response and Data Utilization - The "space taxi" model allows for rapid scheduling and data sharing among remote sensing satellites, transforming dispersed data into actionable disaster monitoring information [2]. - By 2025, the National Space Administration is expected to conduct 159 domestic and international remote sensing emergency disaster monitoring operations, completing over 5,700 satellite imaging tasks and providing more than 23,000 high-quality remote sensing images domestically and over 1,600 images internationally [2].
