The reporter was informed on March 2 that China Aerospace Science and Technology Corporation is deploying a constellation of low-orbit communication satellites. In the first phase of the project, 54 satellites will be built, and then the second phase of the project will be completed to achieve a smooth transition of system capacity, and the number of satellites will eventually exceed 300.
Bao Weimin, member of the National Committee of the Chinese People's Political Consultative Conference and director of the Science and Technology Committee of China Aerospace Science and Technology Group, said that he plans to launch the global mobile broadband satellite Internet system this year. Upon completion, it will become a seamlessly covered spatial information network infrastructure for the world, providing Internet transmission services for all types of terminals such as fixed-surface, hand-held mobile, on-board, on-board, and airborne.
Bao Weimin said that this satellite Internet system can realize broadband communication support capability in the deep sea, the north and south poles, and the “Belt and Roadâ€. Through this system, anyone or thing at any location on the planet can interconnect information at any time.
The Global Mobile Broadband Satellite Internet System will implement six applications:
——Intelligent terminal communication, support commercial mobile phone to directly access satellite constellation, provide high-definition voice service, WeChat and other instant communication services and e-mail services, which can be applied to scientific investigation, geological exploration, disaster relief, emergency support and other scenarios;
——Internet access, providing low-latency data service capabilities, enabling users to enjoy an online experience similar to terrestrial networks, serving markets such as field operations, distance education, and telemedicine;
——Internet of Things access, serving low-energy micro-chemical networking terminals, facing the industrial needs of environmental monitoring, ocean logistics, traffic management, hazardous chemicals monitoring, etc., to achieve the combination of traditional industries and information industry;
—— Hot spot information push, using the characteristics of satellite wide-area coverage to realize real-time broadcast and push of information such as cultural propaganda, disaster warning, weather broadcast, traffic broadcast;
——Navigation enhancement, forwarding Beidou satellite differential correction information, providing more accurate and reliable location services for airborne and vehicle positioning terminals, meeting the needs of unmanned driving, precision agriculture, drone control and so on;
——Aeronautical navigation monitoring, to achieve global cycle tracking of aircraft and ships, provide statistical data value-added services, and improve the safety and reliability of global transportation capacity.
