More recently, Falcon IX rockets carried two small satellites – Tintin-a and Tintin-b – on a regular launch mission, which are test stars for the StarLink program, Communication test. The project plans to launch nearly 12,000 small satellites by 2024 to launch high-speed Internet services to the world.

However, we do not hurry to find Musk to WIFI password, our country’s space-based Internet is also under construction.

Reporters learned from China Aerospace Science and Technology Corporation, the group plans to fully launch this year, the global mobile broadband satellite Internet system construction. The system is a constellation of communications satellites deployed in low orbit. The first phase of the project will launch 54 satellites and the second phase of the project will be implemented in the first phase to achieve a smooth transition of system capacity with more than 300 satellites.

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 and to realize wide and narrowband combined communication and security capabilities in the deep ocean, north and south poles, “Belt and Road” and other regions. With such a seamlessly-covered system around the world, anyone anywhere in the world, or any object, can connect to information at any time.

This reporter has learned that the global mobile broadband satellite Internet system will achieve six applications: First, intelligent terminal communications, support for direct access to commercial satellite mobile satellite constellation, providing high-definition voice services, WeChat and other instant messaging services, e-mail services ; Second, the Internet access, providing low-latency data service 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 medical service protection; third is the Internet of Things And serve the terminal of low-energy miniaturization IOT, focusing on the needs of 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, meet no Vehicle driving, UAV control, precision agriculture, construction machinery market demand for development; Sixth, aviation surveillance, to achieve the global aircraft, ships full-cycle tracking, provide statistical value-added services to meet the growing needs of the development of aviation and maritime markets, To achieve safe and reliable global transport capacity.

According to Zhang Zhongyang, member of the CPPCC National Committee and president of the China Academy of Aeronautics and Astronautics, the Hongyun project being promoted by CASIC will launch the first technology verification star in 2018 and carry out demonstration and demonstration of low-rail broadband communications demonstration.

“Hongyun project construction follows 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 networking trials and run the business trial system by 2020. 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 navigation enhancement and real-time remote sensing support. “By that time, no matter where we are in the desert, the sea or the plane, we can enjoy the same internet speed and service experience as our own home,” he said.

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 onboard broadband, and multi-channel phase shifting chips. Broadband satellites The smallest communication terminal, the smallest power consumption, the lightest weight. The system uses a flexible and controllable satellite communication beam physical fitness, flexibility to adapt to changes in frequency and technological evolution of the impact of ongoing upgrades.

When completed, the system will bring significant benefits in all aspects. Zhang Zhongyang said that in terms of economy, it can provide large-scale services to vehicles at home and abroad, aircraft, ships, etc., and enhance the reliability of smart driving and unmanned control while bringing about rich information products. In terms of social benefits, it can provide services to any area in the country Provide network access means to enhance access to information for young and poor in poor areas, provide rapid response to disasters in areas of communication security, rapid response and accurate command, provide supervision and control of vehicles, ships, navigation aircraft, means of positioning, regulate the industry Ecology, providing data return for environmental monitoring sensors and contributing transmission channels and information sources for the construction of digital China.

Speaking of foreign technology development, Zhang Zhongyang believes that SpaceX’s innovation, the spirit of the challenge is worth learning, the star chain plan handwriting great. Although the number and size of satellites of Hongyun Project are similar to those of Hongyun Project, the functions ultimately realized are the same. He said Rainbow Cloud Engineering will continue to innovate and strive to seize the commanding heights of low-band broadband mobile communications in the commercial space field, contributing China’s space and wisdom to the world.
