He served as the deputy general commander of China's manned space program (1999-2002), led and organized the development and test of test ships and launch vehicles, and completed the launch and recovery of shenzhou I and ii. Weapons and equipment to develop the first as a group company at the same time, realize the continuous key defense weapon equipment first flight and test success, completed the new model and important stage of setting up a development task, realizes the five new satellite first launch successfully. Led and organized the establishment and implementation of several major space projects, actively promoted the management and innovation of space engineering, and made significant contributions to the sustainable development of China's space industry.Yirong Wu is currently the director of Aerospace Information Research Institute, Chinese Academy of Sciences (AIR), and the academician of Chinese Academy of Sciences. He received his BSc and MSc from Beijing Institute of Technology in 1985 and 1988 respectively, and his PhD from Institute of Electronics, Chinese Academy of Sciences (IECAS) in 2001. He joined the IECAS in 1988. He is the leading expert in the realm of information science in China, and he has been making an important contribution to the development and progress of information science and technology in China. He has published over 100 papers in the field of information science, and he is the member of Degrees Committee of the State Council. He has been in charge of several national major projects, and he has won the National Prize for Progress in Science and Technology for several times.  He is the chief scientist of the National Basic Research Program of China (973 Program), and the information technology expert of the National High Technology Research and Development Program (863 Program). He is currently the Editor-in-Chief for Journal of Electronics & Information Technology, Microsystems & Nanoengineering, and Journal of Radars.Jianya Gong is the surveying and mapping and geographic information scientist. In 2011, he was elected as a member of the Chinese Academy of Sciences. Professor of Wuhan University. Former Chairman of the Sixth Committee of the International Society of Photogrammetry and Remote Sensing. Mainly engaged in geographic information theory and geometric remote sensing basic research. In the early 1990s, the concept and data model of object-oriented GIS were proposed. It has now become the mainstream technology of GIS software, and it has taken the lead in the development of object-oriented GIS software GeoStar, which has been widely used in many fields such as mapping, land and power management in China. In terms of photogrammetry and remote sensing, he proposed the generalized geometric imaging model and accurate processing method of remote sensing, presided over the development of China's remote sensing satellite ground processing system, and greatly improved the self-positioning accuracy of domestic remote sensing satellite images. He has won 1 first prize for national scientific and technological progress, 3 second prizes, and 1 Dolezal Achievement Award from the International Society for Photogrammetry and Remote Sensing (ISPRS).
