Satellite Internet is an important part of the next generation of 6G communications, a key support for the realization of the integration of space, space and space, and the interconnection of everything, and an important engine of new quality productivity. It will extensively empower smart agriculture, aviation interconnection, marine monitoring, autonomous driving, and low altitude economy, and help China seize the commanding heights of future scientific and technological competition. This year's Report on the Work of the Government specifically proposed for the first time "accelerating the development of satellite Internet", which is a major upgrade at the national strategic level, indicating that satellite Internet has become the core of the integrated space space information infrastructure and the key base for the development of new quality productivity. What is Satellite Internet? Simply put, when we use mobile phones and computers to access the internet, we mainly rely on signals from base stations on the ground. And satellites are like mobile base stations in space, so whether you are in deep mountains, deserts, oceans, or places without ground base stations, you can connect to the network through satellites. Satellite Internet is mainly composed of space segment, ground segment and user segment. Satellite groups in space are responsible for receiving and transmitting signals; The ground station is responsible for managing satellites and processing signals; The terminal in the user's hand directly sends and receives signals. With the cooperation of the three, satellite Internet can build an integrated space space information network covering the world, enabling high-speed Internet access anywhere in the world. Why develop satellite Internet? The primary goal is to fill in the gaps in coverage. Although China has achieved "broadband connectivity in every village and 5G connectivity in every county", ground communication relies on base stations and fiber optics, making it difficult to lay and costly to operate in areas such as oceans, deserts, plateaus, and remote villages. Therefore, there are still a large number of signal blind spots. Public data shows that nearly one-third of the global population still lacks internet access. However, satellite Internet is not restricted by geographical conditions, and it is complementary and integrated with ground communication, which can solve the "last mile" problem of network coverage, narrow the digital gap between urban and rural areas and regions, and allow remote areas to share digital dividends. From a national strategy perspective, this is an important support for ensuring national space security. Satellite orbit and frequency resources are limited. Following the first come, first served principle, the earlier the layout is made, the more advantageous positions can be seized, and the initiative can be gained for future development. Currently, the demand for satellite communication in scenarios such as ocean operations, scientific research, and aviation broadband is becoming increasingly prominent. Building an independent and controllable satellite Internet can get rid of dependence on foreign technologies and services and ensure the security of key information infrastructure. At the same time, when ground communication base stations are damaged or interrupted due to disasters such as earthquakes and floods, it can also provide safe, independent, stable, and reliable communication support, enhancing China's ability to respond to emergencies and complex environments. From an economic perspective, this will open up new growth opportunities. Satellite Internet involves satellite development, rocket launch, ground equipment manufacturing, terminal application and operation services, and can form a complete aerospace and digital industry chain. If China's satellite Internet has the advantage of global coverage, it will enhance China's competitiveness and influence in the field of global digital services. Satellite Internet is an important part of the next generation of 6G communications, a key support for the realization of the integration of space, space and space, and the interconnection of everything, and an important engine of new quality productivity. It will extensively empower smart agriculture, aviation interconnection, marine monitoring, autonomous driving, and low altitude economy, and help China seize the commanding heights of future scientific and technological competition. All countries are actively deploying satellite Internet. Space has become the main battlefield of global science and technology competition, and satellite Internet plays a prominent strategic role in the process of improving the capability of the global aerospace industry and rapidly expanding the market scale. Morgan Stanley predicts that by 2040, the global space economy market will exceed $1 trillion, and satellite broadband will account for 50% to 70% of the expected growth of the space economy, becoming a white hot field in the space economy. Public data shows that foreign Starlink has deployed over 8400 satellites, with over 6 million users and covering 150 countries. With the technological progress, the cost of satellite Internet investment has dropped significantly, and large-scale application and industrial development usher in an important opportunity period. China's satellite Internet layout has entered a critical stage of large-scale networking and industrialization. The State Administration of Market Supervision recently approved the establishment of the National Satellite Internet System and Service Standardization Technical Committee, which will continuously improve the satellite Internet standard system and promote the high-speed, standardized and healthy development of the satellite Internet industry. China has actively applied for orbit and frequency resources, accelerated constellation networking, and increased launch frequency, laying a solid foundation for satellite Internet construction. In the future, it is necessary to accelerate breakthroughs in scale, cost, frequency trajectory, industrial chain, ecology and other aspects, solve technical bottlenecks such as terminal device performance, and comprehensively enhance the level of independent controllability and international competitiveness. Satellite Internet is not only a global communication network, but also a strategic network to ensure national security and an industrial network to drive future development. Accelerate the independent networking, improve the standard system, and conquer the core technology. The "Star Sea" of satellite Internet will bring together a new space picture that connects heaven and earth and benefits thousands of families. (New Society)
