China News Service, Beijing, May 12 (Guo Chaokai) reporter learned from China Aerospace Science and Industry Group Co., Ltd. that at 9:16 on May 12, Beijing time, Kuaizhou No. 1 A carrier rocket was at the Jiuquan Satellite Launch Center, The "Two Arrows" method put two satellites, "01" and "02", "Xingyun 2" into the scheduled orbits, and the launch mission was a complete success.

The successful launch of 01 and 02 stars of "Xingyun 2" marked another major progress in the China Aerospace Science and Industry Corporation's "five clouds and one car" series of commercial aerospace projects. As the starting star of the China Space Science and Technology Space-based Internet of Things constellation, "Xingyun 2" officially launched on-orbit technology verification and application testing.

The 01 and 02 stars of "Xingyun 2" launched this time are two technical verification stars of the "Xingyun Project" alpha phase. They were independently designed and developed by the Aerospace Sanjiang Aerospace Xingyun Technology Co., Ltd., a subsidiary of China Aerospace Science and Technology. Independent innovation has been achieved in many important technical fields such as inter-satellite laser link technology, spaceborne digital multi-beam communication payload, and air-ground satellite communication protocol. After the satellite enters the predetermined orbit, it will provide application testing for many industries such as smart container supervision, polar environment monitoring, geological disaster monitoring, meteorological data forecasting, marine environment monitoring, and marine transportation communications, and will lay the foundation for the subsequent networking of the space-based IoT basis.

According to reports, the "Xingyun Project" plan is divided into three phases of α, β, and γ. A space-based IoT constellation composed of 80 low-orbit communication satellites will be built around 2023 to solve the current ground IoT business due to cellular communication networks. The serious lack of coverage (land coverage is about 20% and ocean coverage is less than 5%) leads to the "communication blind spot" problem, to achieve a truly global interconnection of all things.

The Kuaizhou-1A launch vehicle that carried out the launch mission was developed by the Aerospace Science and Technology Rocket Technology Co., Ltd. It has the characteristics of high flight reliability, high orbit accuracy, short preparation period, low support requirements, and low launch cost. , Mainly to provide launch services for 300 kg low-orbit small satellites. As a mature solid launch vehicle, Kuaizhou-1A rocket has successfully completed 8 launch missions.
This launch is the first "combination" of Kuaizhou rocket and Xingyun satellite. To ensure the smooth progress of the launch mission, Sanjiang Aerospace has overcome the challenges brought about by the new coronary pneumonia epidemic and actively and orderly promoted the resumption of production. It is worth mentioning that the aerospace Sanjiang named the "Xingyun II" 01 star launched this time as "Xingyun • Wuhan", and by painting "Heroic Wuhan • Great China" and "Salute" on the rocket body The group portrait of medical workers pays tribute to Wuhan, the people of Wuhan and the majority of medical workers.
