Global mobile broadband satellite Internet system is about to start construction
The reporter learned from China Aerospace Science and Technology Corporation that the group plans to launch the construction of the global mobile broadband satellite Internet system this year in an all-round way.The system is a communications satellite constellation deployed in low orbit and the first phase of construction will launch 54 satellites and will be implemented subsequently The second phase of construction, to achieve a smooth transition of system capabilities, the number of satellites will be more than 300.
CPPCC National Committee members, Space Technology Group Science and Technology Commission package for the people introduced, the system will be built into a seamless coverage of the world's spatial information network infrastructure for the ground fixed, handheld mobile, car, ship, airborne and other terminals To provide Internet transmission services to enable broadband and narrowband communications coverage in the deep ocean, north and south poles, the 'One Belt and One Road', etc. Through such a seamless coverage system in the world, anyone anywhere on the earth or any Objects, can be achieved at any time information interconnection.
This reporter has learned that the global mobile broadband satellite Internet system will achieve six aspects of application capabilities: First, intelligent terminal communications, support for commercial mobile phone direct access to the satellite constellation, providing high definition voice services, WeChat and other instant messaging services, e-mail services ; Second, the Internet access, providing low-latency data services capabilities, enabling users to enjoy the Internet and the ground network similar to the experience for the field operations and offshore operations and other markets, to achieve distance education, remote health care services protection; third is the Internet of Things And serve the terminal of low energy consumption miniaturization IOT, and focus on developing new industries such as environmental monitoring, ocean logistics, hazardous chemicals monitoring, traffic management, smart ocean and so on. Fourthly, push hot information and make full use of the characteristics of satellite wide area coverage to achieve Fifth, the navigation enhances and forwards the Beidou differential correction information to provide more accurate and reliable information for airborne and vehicular positioning terminals Location service to meet unmanned car driving, drones, Quasi agriculture, engineering machinery market development needs; Sixth, aviation and maritime surveillance aircraft to achieve a global, full-cycle tracking of ships, providing statistical data value-added services.
Rainbow Cloud project this year to launch technology verification star
According to Zhang Zhongyang, member of the CPPCC National Committee and president of the China Academy of Aeronautics and Astronautics, the Aerospace Science and Technology is going to launch the first cloud technology verification satellite in 2018, demonstrating and demonstrating low-level broadband communications demonstration and application.
'Rainbow cloud construction in accordance with the three-step strategy.'Zhang Zhongyang said that after the completion of the first step this year, the second step is to launch four commercial trial star network trial run in 2020 to complete the business test system in 2022, China will deploy and operate the entire constellation and construct a space-based broadband Internet network consisting of 156 satellites to form a comprehensive information system for communications, navigation and remote sensing with low-rail broadband communications and capable of navigating enhanced and real-time remote sensing support. 'By then, Whether we are in the desert, the sea or the plane, we can enjoy the same internet speed and service experience at home. '
This reporter has learned that Rainbow Cloud Engineering is highly advanced and will become the world's first low-band Ka broadband communication system and will be the first in the world to adopt technologies such as broadband inter-satellite communications, broadband on-board broadband, and multi-channel phase shifting chips. Broadband satellites The smallest communication terminal, the smallest power consumption, the lightest weight.
Speaking of foreign technology development, Zhang Zhongyang think SpaceX innovation, the spirit of the challenge is worth learning, the star chain plan handwriting great.Hongyun project although the number and size of small satellite, the goal is consistent with the ultimate realization of the same function.
