Xinhua News Agency, Hangzhou, May 14 (Reporters Zhu Han and Song Chen) He sent artificial intelligence to space to empower satellites to process ground observation data in real time in orbit, and support scientists to explore more unknowns.

　　The reporter learned from Zhijiang Laboratory, a new R&D institution in Zhejiang Province that with the successful launch of the space computing satellite constellation at Jiuquan Satellite Launch Center on the 14th, the "Three-Body Computing Constellation" of my country's full-orbit interconnected space computing constellation has officially entered the networking stage.

　　This is the first launch of the "Three-Body Computing Constellation" led by Zhijiang Laboratory, and it is also the first launch of the "Star Computing" program of Guoxing Aerospace. The 12-star shooting shot was launched this time, with the highest single-star computing power of 744 TOPS (744 trillion calculations per second), and the overall computing power of 5 POPS (50 trillion calculations per second) and 30TB of storage capacity. The "Three-Body Computing Constellation" is a space computing infrastructure with a scale of 1,000 stars jointly created by Zhijiang Laboratory and global partners. After completion, the total computing power can reach 1,000 POPS (10 billion calculations per second).

　　In the command and control hall of the "Three-Body Computing Constellation" of Zhijiang Laboratory, the reporter saw that the first set of telemetry data of the first satellite has been successfully transmitted, and the scientific research team has been working tirelessly to work.

　　According to reports, usually, satellites need to transmit data back to the ground first, and then analyze it by the ground data processing center. However, this "sky-sense and earth calculation" model is limited by factors such as ground station resources and bandwidth. Less than one-tenth of the effective satellite data can be transmitted back to the ground, and there are problems such as poor data ageing. Solving these problems is the starting point of the "Three-Body Computing Constellation".

　　It is understood that the 12 computing satellites launched in orbit this time are equipped with satellite-borne intelligent computing systems and inter-satellite communication systems, which can realize the interconnection of the entire orbit satellite, have space-on-orbit computing capabilities, and will build an integrated network of heaven and earth. The satellite is also equipped with a space-based model with 8 billion parameters, which can process L0-L4-level satellite data in orbit and will perform in-orbit test tasks such as laser access for different orbit satellites and astronomical observations.

　　"To form a space computing constellation and let the constellation fully exert its value is a very large and extremely complex system project. Organized scientific research and organized achievement transformation and other mechanism innovations are important guarantees." Tong Guili, Secretary of the Party Committee of Zhijiang Laboratory, said.

　　According to Li Chao, deputy director of the Space-based Computing System Research Center of Zhijiang Laboratory, Zhijiang Laboratory has undertaken the development of space computing software and hardware and space-based models such as satellite-based intelligent computers, and Guoxing Aerospace has undertaken the development of intelligent connected satellite platforms and the development of the whole satellite for the first time.

　　Wang Jian, an academician of the Chinese Academy of Engineering and director of Zhijiang Laboratory, said that the construction of the "three-body computing constellation" will greatly expand the boundaries of space applications and have far-reaching significance for the transformation of the aerospace industry.
