Yesterday (December 12), kuaizhou-1a carrier rocket launched two satellites of “xingyun-2” 01 / 02 into the predetermined orbit by “one arrow and two satellites” at Jiuquan Satellite Launch Center. This is the first time that the kuaizhou rocket and Xingyun satellite have been combined, and it is also China’s first satellite Internet of things project. It is pointed out that the successful launch of “xingyun-2” 01 / 02 marks another progress in commercial aerospace engineering of “five clouds and one vehicle”. As the first star of China Aerospace Science and industry space-based Internet of things constellation, “xingyun-2” has officially launched in orbit technology verification and application test.

The launch of “xingyun-2” 01 / 02 satellite is the two technology verification stars of “Xingyun project” phase a. “Cloud Engineering” is one of the “five clouds and one car” project of Feiyun, kuaiyun, Xingyun, Hongyun, Tengyun and high-speed flying train. In the past three years, it has focused on the development of commercial aerospace industry with technological innovation, business model innovation and management innovation, and has achieved a series of achievements.

  

It is reported that “Xingyun project”, as the first space-based Internet of things constellation that China has announced its own investment and construction, plans to build a space-based Internet of things constellation composed of 80 LEO communication satellites around 2023 in three stages of α, β and γ, so as to solve the problem of “communication blind area” caused by the serious insufficient coverage of cellular communication network in ground IOT business.

  

With the advantages of large system capacity, strong service ability, long transmission distance, strong real-time performance, independent, reliable and safe, “xingyun-2” satellites 01 and 02 will provide application tests for intelligent container supervision, polar environment monitoring, geological disaster monitoring, meteorological data forecasting, marine environment monitoring, maritime transportation communication and other industries, and lay a foundation for the subsequent networking of space-based Internet of things Set the foundation.

It is understood that “xingyun-2” satellites 01 and 02 have adopted inter satellite laser link technology for the first time in China’s domestic LEO constellation, that is, long-distance communication can be realized between satellites in orbit through laser communication technology, which can not rely on the transmission of ground stations, so as to improve the real-time communication service. In addition, for the first time in China, the two satellites have adopted the spaceborne digital multi beam communication payload. Through the advanced communication protocol, the satellite massive short data access is realized, thus becoming the earliest constellation system to realize the integration of operation, management and service in China.

Experts said that the dual-mode container supervision terminal independently developed by Xingyun company can also provide timely, data-based and intelligent location information, track tracking, status monitoring, drug safety and other supervision services for the drug cold chain logistics supervision, such as maritime or land transport containers, logistics vehicles, etc., so that the cargo owners, vehicle owners and supervisors can master the location information of cold chain goods in real time Security information status. At present, Xingyun company focuses on marine, oil, electric power, geological disaster, meteorology, emergency and other key industries for pilot application, and has developed more than 100 potential customers. The market application prospect of space-based Internet of things will be very broad.
