China's satellite remote sensing still faces the development dilemma of 'big industry, small industry'. From the perspective of user needs, there are three major problems: 'not useful, not good at using, and not affordable'. It is necessary to propose a systematic solution from the following three dimensions: 'business model' changes from 'small number of users + low frequency and high price' to 'massive users + high frequency and low price', 'business carrier' to create an open remote sensing data aggregation and public service commercial platform, 'technical facilities' to build a new satellite system with remote sensing full-time and full coverage through communication satellites. The fundamental logic of this scheme follows the development law of the digital economy, gives full play to the sharing and reuse value of data elements, and forms a platform sharing economy based on remote sensing big data; the external development opportunity lies in the emergence of low-orbit giant communication satellite constellations, providing the key conditions for 'jumping out of remote sensing for remote sensing'. The newly imagined communication + sensing satellite system has an investment of hundreds of billions in remote sensing payloads, and the annual revenue of public services in the domestic market (mainly C-end users) is expected to reach the billion level, which can quickly realize the closed-loop investment and profit model; in the expansion of public users, satellite remote sensing can complement and complement satellite communication business, and jointly penetrate the billion-level mass communication users, with strong commercial cooperation. Feasibility; in the future, based on continuous monitoring in time and space and real-time remote sensing services, using the carrier of commercial remote sensing public service platform, satellite remote sensing still has a huge value creation space in the B-end user market. Therefore, we should seize the opportunity, do a good job in top-level design and overall resource coordination, and lead the transformation and development of China's satellite remote sensing industry through innovative system arrangements.
