“…High-resolution satellite imagery, due to its rich information content and complex texture, faces challenges in achieving high compression ratios and reconstruction quality, making it difficult to adapt to the limited computational capabilities and transmission bandwidth available on satellites. Consequently, this paper proposes a technique for sparse representation and high-rate on-orbit compression of satellite remote sensing imagery [14], [15]. By exploring the sparse characteristics of high-dimensional remote sensing data, this technique achieves high-rate on-orbit compression, effectively addressing the transmission delay issues caused by bandwidth limitations.…”

Luojia 3-01 is the world's first intelligent remote sensing satellite, equipped with various imaging modes including video, frame-pushing, and scan-pushing. It boasts sub-meter level multi-mode optical imaging capabilities, on-orbit intelligent processing, and real-time intra-satellite and satellite-to-ground data transmission. Throughout the satellite's design and development, we have established the real-time intelligent information service architecture for Luojia 3-01, marking a new paradigm in on-orbit processing and real-time services for intelligent remote sensing satellites. We have proposed the onorbit real-time processing architecture of Luojia 3-01, addressing the challenges of limited computational and storage resources, particularly in on-orbit processing of vast volumes of remote sensing data, including core algorithmic bottlenecks in 'correction-extraction-compression'. A novel intelligent remote sensing satellite system has been developed, featuring multi-mode imaging, an open platform, intelligent processing, and satellite-toground interconnectivity, which significantly reduces the response time of remote sensing services to less than 8 minutes, thereby shortening the cycle from data acquisition to intelligent information service. This innovation spearheads a technological leap in remote sensing satellite services from data to information, from post-event to real-time, and from professional to widespread public applications, laying a solid foundation for the popularization and commercialization of China's intelligent remote sensing satellites.
