Space network is the focus of space competition, which will lead to extensive changes in information, economy, society, and military. It requires forward-looking layout to provide technological support for China to strive for and maintain its technological advantage in the field of information networks. Based on the development of broadband satcom networks, the following suggestions are proposed.
Develop a long-term plan for broadband satcom networks, build a technologically advanced, nationwide, and efficiently operated national space infrastructure, and form the backbone architecture of future space networks. The selection of the technical route of the Chinese satellite network should be closely integrated with the user group to form a suitable solution.
In line with China's national conditions, compared with the B2C (Business to Consumer) service model of Oneweb and Starlink, the B2B (Business to Business) service model prioritizing industry or enterprise users is more valuable and can achieve high-quality network access and backbone interconnection service capabilities.
Promote the commercialization of satcom communication, deepen the integration of airborne information networks, future Internet, and mobile communication networks, and form an integrated information network that covers the whole world and extends to space.
Promote the entry of ground industry chain into aerospace field, explore the mode and technological development paradigm of applying intelligent, information and network technology more efficiently in the development of broadband satcom networks.
Strengthen the driving role of experiments on applications, establish a network testbed that supports technological innovation and verification, and demonstrate and verify space networks for space and ground scientific activities and major actions.
Strengthen the research and support for high-end satellite-borne processors and operating systems that constrain the development of broadband satcom communication technology, including space-grade large-scale field programmable gate arrays (FPGA) and next-generation high-performance processors, to achieve independent and controllable core components and software, and lay a solid physical foundation for the new technology system of broadband satellite networks.
Broadband satcom networks are a microcosm of the rapid development of satcom communication. It can be foreseen that in the next 10 years, space infrastructure represented by broadband satcom communication networks will become a new battlefield for international space powers to compete. To maintain China's advantage in the field of information networks and lead global information network technology and space technology innovation requires systematic planning and comprehensive consideration.
