从根本上提升用户数据获取效率和卫星利用率

Group 1 - The National Data Bureau has released a total of 70 demonstration scenarios in three batches and announced a fourth batch of 30 scenarios to maximize the value of public data [1][2] - The data supply method has shifted from "mainly sharing" to a combination of "sharing, opening, and authorized operation" in the fourth batch, with authorized operation becoming a significant data supply method [1][2] - The introduction of specialized forces for data processing and governance through authorized operation has effectively balanced data circulation and security, allowing more data to be shared safely [1] Group 2 - 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 [2] - By 2025, China plans to conduct 159 domestic and international remote sensing emergency disaster monitoring operations, completing over 5,700 satellite imaging tasks and providing over 23,000 high-quality remote sensing data images domestically and over 1,600 images internationally [2] - The "space star" model for coordinating civil and commercial satellites has significantly improved the emergency response speed for satellite observation, transforming dispersed data into actionable disaster prevention and mitigation monitoring data [2]
