Core Viewpoint - The "Star Eye Payload," developed by Nanjing University of Aeronautics and Astronautics, is China's first space-based computing device for on-orbit positioning of ground radiation sources, showcasing significant innovation and technical capability in response to national strategic needs [1][2]. Group 1: Project Overview - The "Star Eye Payload" achieved on-orbit identification and positioning of ground radiation sources through signal collection, optical remote sensing imaging, and space-based computing [1]. - The project won first prize at the 20th National Graduate Electronic Design Competition, marking a historic breakthrough for Nanjing University of Aeronautics and Astronautics [1]. Group 2: Technical Innovations - The team integrated three major functions—"RF tracking," "image matching," and "space-based computing"—into a single system called "Three-in-One Detective" [2]. - The payload features a machine learning-based small target detection technology, enhancing its capability to intelligently identify star maps [2]. - A domestic Loongson processor-based cloud system was deployed in the payload, enabling it to perform 100 trillion calculations per second, providing it with significant computational power [2]. Group 3: Development Challenges - The team faced a tight timeline of only 18 months from project approval to launch, requiring extensive testing and validation of hundreds of parameters [2]. - Initial flight tests did not yield successful positioning results, prompting the team to conduct multiple analyses and tests to identify and rectify the issues [3]. - The team encountered severe weather challenges, including a super typhoon, which necessitated arduous travel and working conditions to complete testing tasks [4]. Group 4: Team Composition and Leadership - The "Star Eye Payload" team consists of members from various educational backgrounds, including undergraduates, master's, and doctoral students, showcasing a blend of experience and youth [4]. - Key leadership roles were filled by Professor Li Guangxia as the overall expert and Professor Cheng Jian as the chief designer, both of whom played crucial roles in overcoming project challenges [4].
