With the advances of small satellite technology in commercial space sector, using small satellite networks to form a satellite constellation and conduct commercial operational services has entered into a vigorous phase of de velopment. As small satellite technology develops, problems in the operations of small satellite constellations are also gradually emerging. These include ground measurement and operational control systems for small satellite constella tions, the commercial operational mode, support and the guarantee of laws and regulations related to small satellites. This report discusses the development of commercial space small satellite operation industrialization, explores the small satellite operational modes and technological innovation, proposes the commercial space industry chain to build the industry ecology. At the same time, it looks forward to the integration of space and terrestrial communication. It also calls on relevant organizations of China to speed up the process of space legislation, formulate the relevant policies to encourage the operations of small satellites in commercial space sector, and push China’s commercial space to a new level.
