科技日报：“三体计算星座”为啥把计算送上天

Core Viewpoint - The launch of China's first integrated orbital computing satellite constellation, "Three-Body Computing Constellation," marks a significant advancement in space computing capabilities, aiming to enhance data processing efficiency in various applications [1][2]. Group 1: Naming and Concept - The term "Three-Body" is derived from Newton's "Three-Body Problem," representing the complex interactions among multiple objects, akin to celestial bodies [2]. - The "Three-Body Computing Constellation" is classified as a fourth type of artificial satellite, focusing on computational tasks rather than traditional communication, navigation, or remote sensing [2][3]. Group 2: Purpose of Space Computing - Traditional satellite data processing involves sending data back to Earth, which is limited by ground station resources and bandwidth, resulting in low data transmission efficiency [4]. - The "Three-Body Computing Constellation" aims to perform data processing in orbit, allowing for immediate transmission of processed results to Earth, thereby expanding the boundaries of space applications [4][5]. Group 3: Technical Specifications and Capabilities - The initial launch includes 12 computing satellites, which are the first step in building a constellation with a total computing power of 1000 Peta Operations Per Second (POPS) [5]. - The onboard intelligent computing system enhances satellite computing power from Tera to Peta scale, achieving a 10 to 100 times improvement [5]. - The constellation will utilize an 8 billion parameter space-based model, enabling autonomous multi-source remote sensing data processing in orbit [5]. Group 4: Future Applications - The "Three-Body Computing Constellation" is expected to significantly reduce data processing times in applications such as forest fire monitoring, from hours to minutes or even seconds [7]. - Future applications will include urban governance and emergency response, providing effective data support and intelligent services for smart city development [7]. - The laboratory plans to complete the deployment of over 50 computing satellites this year and aims to establish around 100 satellites by 2027 [7].
