Currently, the global aerospace information industry is accelerating its transition toward commercialization. Technological advances and reduced costs are encouraging an increasing number of companies to enter the aerospace information sector, driving the marketization and intensifying the competition in the industry. The rapid development of China's aerospace industry in recent years has led to an initially scaled market. Further developing the commercial aerospace information industry is crucial for strengthening the aerospace sector of China. Based on the development status of China's commercial aerospace information industry and focusing on space application, this study summarizes the main architecture and development trends of China's commercial aerospace information industry. Moreover, it identifies the key technologies that support the high-quality development of the industry, involving satellite-payload integrated manufacturing, advanced photoelectric payloads, high-speed and high-security communications, as well as advanced remote-sensing data products and services. After reviewing the current status and existing problems of China's commercial aerospace information industry, we propose the following suggestions: (1) building an industry development ecosystem, (2) supporting downstream enterprises regarding data processing and application, (3) promoting the commercialization of aerospace information, (4) fostering talent aggregation, (5) expediting the transformation of scientific and technological achievements, and (6) deepening production-education-research cooperation.
