Abstract: Traditional satellite remote sensing data acquisition, processing, and application models can no longer meet the demands of populism and real-time applications. In order to meet the real-time intelligent service demand for space-based information in the era of Internet of Things, it is of strategic significance to construct a positioning, navigation, timing, remote sensing, communication (PNTRC) integrative space-based information real-time service system that is system-connected, spatio-temporally fused, and service-oriented. This system supports users of all kinds to obtain information, high-precision positioning and timing, and multimedia communication services anytime and anywhere. Wuhan University has deployed the Luojia series of scientific experimental satellites to verify the integrated intelligent remote sensing satellite technology. In order to further promote the construction of the PNTRC system in China, Wuhan University, in cooperation with the Yantai Municipal Government in Shandong Province, has proposed the Oriental Smart Eye intelligent remote sensing satellite constellation plan. This plan aims to achieve innovative service mode transitions in satellite remote sensing, spanning government, industries, and the general public, by utilizing key technologies such as integrated positioning, navigation, timing, remote sensing, communication, satellite constellation network observation, on-orbit processing, and artificial intelligence. It aims to open up the blue ocean market of commercial remote sensing.
