摘　　要：5米光学02星于2021年12月26日成功发射,卫星与前序型号组成陆地中分业务卫星星座,建设形成天地一体化大幅宽定量化综合对地观测能力。在轨测试期间,自然资源部根据卫星设计指标要求,围绕土地资源、地质矿产、测绘地理信息、海洋海岛监测等领域业务,梳理共计32个业务测试项,并按照自然资源调查和监测的相关标准和技术规范,开展了应用测试评价工作。在轨测试表明,卫星系统、地面系统和应用系统各项功能正常、运行稳定,双星一致性好,具备组网运行条件,卫星数据质量可满足自然资源执法督察、地质矿产资源调查、生态修复工程跟踪评价、地理空间信息更新、围填海调查、海岸线变化监测、钢铁去产能等业务需求,高光谱和热红外载荷定量应用测试取得良好效果。本文在介绍该卫星的数据特点与应用能力的基础上,重点介绍和分析卫星在轨测试应用评价结果,可为后续业务化应用提供参考。The 5 m Optical Satellite 02(ZY1-02E)was successfully launched on December 26,2021.Along with the previous model(ZY1-02D),an operational constellation of mid-resolution satellites will be established,forming a large-scale,quantitative,and comprehensive earth observation capability.This satellite was designed to provide 2.5 m panchromatic/10 m multispectral,30 m hyperspectral,and 16 m thermal infrared image data.The whole project was led by the Ministry of Natural Resources.It will support national monitoring and survey and mapping projects at the scale of 1∶100000—1∶250000.Compared with traditional multispectral data,hyperspectral data can obtain more abundant spectral information of ground objects,which is particularly important for fine-grained survey and monitoring tasks.The development of China’s hyperspectral remote sensing technology is basically synchronized with the international frontier level.However,since the birth of hyperspectral remote sensing technology,the main way to obtain data has relied on human-operated aerial platforms,and for a long period of time,there has been no large-scale acquisition capacity from the data source.Therefore,the hyperspectral payload carried by this satellite is its biggest highlight and has attracted widespread attention from domestic and foreign peers.During the in-orbit test,the Ministry of Natural Resources designed a total of 32 application test items,focusing on land resources,geology and minerals,surveying and mapping geographic information,ocean island monitoring,and other fields.All application items and other key indicators were evaluated in accordance with the relevant standards for natural resource survey and monitoring and technical specifications.The result shows that the satellite system,ground system,and application system have been operating stably and maintaining good consistency between each satellite of the constellation.It meets the data quality requirements of main businesses in various fields,including natural resource supervision and enfor
