封面图像为珞珈三号01星（又名双清一号，烟台一号）获取的澳大利亚悉尼港及周边区域视频影像（武汉大学测绘遥感信息工程全国重点实验室王密、戴荣凡和程昫供图）。该影像清晰地呈现了悉尼海港大桥、歌剧院等标志性建筑，以及密集城市建筑、水域岛屿的分布细节，视频成像还可实时监测船舶等动态目标运动状态，充分展现了该卫星在精细获取地表空间信息的能力。珞珈三号01星是全球首颗互联网智能遥感科学实验卫星，于2023年1月15日在太原成功发射，由武汉大学联合航天东方红卫星有限公司等多家单位研制，空间分辨率为0.7 m,幅宽10 km，具备多模（高清视频、立体、连续区域成像）、智能（星上实时处理）、互联（卫星与手机双向通信，服务大众）、开放（在轨算法验证平台，可上注更新APP）四大核心功能。珞珈三号01星集遥感与通信功能于一体，探索了从数据获取到应用终端的测绘遥感信息高效智能服务模式，为遥感数据基于天地互联网的在轨处理与实时传输提供了真实的服务验证平台，对推进我国天基实时智能服务系统（PNTRC）和空间信息网络建设具有重大意义。
The video imagery of Sydney Harbour and its surrounding areas in Australia, acquired by the Luojia3-01 satellite
The cover image shows a video imagery of Sydney Harbour and its surrounding areas in Australia, captured by the Luojia3-01 satellite (Also known as Shuangqing-1 and Yantai-1), courtesy of Wang Mi, Dai Rongfan, and Cheng Xu from the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS) at Wuhan University. The image clearly presents iconic landmarks such as the Sydney Harbour Bridge and the Opera House, while capturing detailed distributions of dense urban buildings, water bodies, and islands. The video imaging also enables real-time monitoring of the motion states of moving targets such as ships, fully demonstrating the satellite's capability to precisely acquire surface spatial information. Luojia3-01 is the world’s first internet-based intelligent remote sensing scientific experimental satellite. It was successfully launched on January 15, 2023, at Taiyuan, China, and was jointly developed by Wuhan University and DFH Satellite Co., Ltd., among other institutions. The satellite features a spatial resolution of 0.7 m and a swath width of 10 km, and integrates four core functionalities: multi-mode imaging (High-definition video, stereo, and continuous regional imaging), onboard intelligent processing (Real-time processing), internet connectivity (Two-way communication between satellite and mobile phones to serve the public), and an open platform (An onboard algorithm verification platform supporting app updates). Luojia3-01 combines remote sensing and communication capabilities, pioneering an efficient and intelligent service model for surveying, mapping, and remote sensing information—from data acquisition to end-user applications. It serves as a realistic service validation platform for onboard processing and real-time transmission of remote sensing data via space–ground integrated networks. This satellite is of great significance for advancing China’s space-based real-time intelligent service system (PNTRC) and the construction of space information networks.
