China News Service, Beijing, May 12 (Guo Chaokai) China successfully launched the "Xingyun 2" 01 and 02 stars at the Jiuquan Satellite Launch Center on the 12th. These two satellites are the starting stars of the "Xingyun Project", which also marks the successful completion of the "Xingyun Project" alpha-phase construction task.

  As China's first space-based IoT constellation that announced independent investment and construction, the "Xingyun Project" plans to build a space-based IoT constellation composed of 80 low-orbit communication satellites around 2023 in three phases, α, β, and γ. To completely solve the current problem of terrestrial Internet of Things business due to the serious lack of coverage of cellular communication networks (land coverage is about 20% and ocean coverage is less than 5%), which leads to the problem of "communication blind spots" and helps customers realize the true global interconnection of all things.

  "Xingyun 2" 01 star and 02 star are independently designed and developed by Aerospace Sanjiang Aerospace Xingyun Technology Co., Ltd. (hereinafter referred to as Xingyun Company) affiliated to China Aerospace Science and Industry Group Co., Ltd., with large system capacity, strong service capacity, and transmission distance The advantages of remote, real-time, independent, reliable and safe, will provide on-orbit application testing for multiple industries such as intelligent container supervision, polar environment monitoring, geological disaster monitoring, meteorological data forecasting, marine environment monitoring, marine transportation and communication, and follow-up The foundation of the space-based Internet of Things is laying the foundation.

  Xingyun experts told reporters that the market application prospects of the space-based Internet of Things are very broad. Currently Xingyun focuses on pilot applications in many key industries such as ocean, oil, power, ground disasters, meteorology, and emergency, and has developed more than 100 potential client.

  For example, the dual-mode container supervision terminal independently developed by Xingyun Company can provide timeliness, data, and intelligent location information, trajectory tracking, status monitoring, and medicine for cold chain logistics supervision of pharmaceuticals such as shipping or land transportation containers, logistics vehicles, etc. Safety and other supervision services allow cargo owners, vehicle owners, and supervisors to grasp the location information and safety information status of cold chain items in real time.

  It is understood that the "Xingyun 2" 01 and 02 stars used inter-satellite laser link technology for the first time in China's domestic low-orbit constellation, that is, between-orbit satellites can achieve long-distance communication through laser communication technology, and can be independent of The transfer of ground stations improves the real-time nature of communication services.

  In addition, the "Xingyun 2" 01 satellite and 02 satellite used the satellite-based digital multi-beam communication payload for the first time in China. Through independent innovative advanced communication protocols, they achieved massive short data access to satellites, which became the earliest domestic implementation. Constellation system with integrated operation, management and service.

  As one of the most challenging and driving high-tech industries in the world today, the aerospace industry is an important part of China's strategic emerging industries and advanced manufacturing. Since the release of the "Five Clouds and One Car" (Feiyun, Kuaiyun, Xingyun, Hongyun, Tengyun Project and High-speed Flying Train Project) commercial aerospace project, China Aerospace Science and Industry Group Co., Ltd. in less than 3 years A series of groundbreaking results have been achieved in the field of commercial aerospace, and the "Xingyun Project" is one of them.
