Beidou was built and he left

It is understood, 1958 In 2007, Xu Qifeng graduated from the PLA Academy of Surveying and Mapping and taught at the school. He has long been engaged in teaching and scientific research in the field of”satellite geodesy and navigation and positioning”. is one of the earliest scholars in China to carry out satellite geodesy and GPS technology research.

He was a member of the”China’s Second Generation Satellite Navigation Major Special Committee of Experts” , National major scientific project”China mainland tectonic environment monitoring network project” expert. Presided over and undertaken more than 20 national defense models and major military scientific research projects, and achieved many research results. His”GPS Navigation and Precision Positioning” is the first monograph on GPS technology in China,“Space Geodesy-Satellite Navigation and Precision Positioning” is listed as a country Level key textbook.

In 2005, Xu Qifeng was elected as an academician of the Chinese Academy of Engineering.

Many years ago, due to the high level of positioning and timing services provided by the GPS system, many people suggested that our country refer to The GPS satellite constellation plan was deployed, but Xu Qifeng insisted against it and insisted on”starting from scratch”, making a valuable contribution to promoting the development of China’s satellite navigation system.

Xu Qifeng once said, Satellite needs positioning, and life needs positioning. He has positioned himself as a “Xu teacher” throughout his life, treating people with humility and perseverance:”If I can still write programs and deduce formulas, I am not old yet, It can also serve the country and the military.”
