Competitive Situation and Enlightenment of Key Technologies of Global Satellite Internet
At present,the world is carrying out a new round of space race around the construction of satellite Internet system,in which LEO satellite communication is the prevailing focus of world powers in the field of space-based information systems after satellite navigation.Studying the key technologies of satellite Internet is of great significance in promoting the progress of satellite and communication technology,addressing global challenges,and leading future development.In this paper,by constructing the key technology system of satellite internet,retrieving patent data,comprehensively analyze the competitive situation of key technologies of satellite internet from the dimensions of technology development trend,technology competition subject,technology competition region and technology competition field.The study found that the development of satellite Internet in China has many problems,such as late start,lack of industrial clusters,low patent conversion rate,and insufficient scenario application.The development strategies are summarized as followings:Anticipate cutting-edge technologies and lay out future technologies to seize emerging cutting-edge fields.Strengthen the research and development of key core technologies,and establish innovative association.Strengthen the deep integration of industry,academia,and research,and build industrial ecological clusters.Highlight the integration of communication,navigation,and remote communication,and create diversified application scenarios.
