Academician Liu Jingnan

Academician Liu Jingnan (left), male, born on July 1, 1943, Han nationality, from Changsha City, Hunan Province, was elected as academician of Chinese Academy of Engineering in December 1999, and served as president of Wuhan University.

Academician Liu Jingnan has been engaged in the research of geodetic coordinate system theory, satellite positioning technology theory and application for a long time. He has unique achievements in the research of satellite geodetic technology and data processing, and is a famous expert in the field of satellite geodesy in China. In the 1980s, he and his colleagues proposed a survey theory called " military survey model" in the world, which solved a series of problems in the field of geodetic coordinate system transformation theory research, thus completing the international academic debate. The joint adjustment software of satellite network and ground network developed by him not only solved the urgent need of oil exploration department at that time, but also created huge economic benefits. In the 1990s, he presided over the development of China' s first GPS (Global Positioning System) commercialized software - " GPS satellite positioning data processing integrated software". At present, the software has been used by hundreds of units at home and abroad, occupying more than 80% of the domestic market, and exported as a proprietary technology abroad. His idea of GPS software design has been widely accepted and adopted by the International GPS commercial software development community, and some of his research results have become the national and Urban GPS survey specifications. He used his own " reverse method" to accurately establish the national plate movement trend. He presided over and completed the overall adjustment project of the national high-precision GPS network, the data processing of the GPS international battle in the Asia Pacific region, and the design, construction and data processing of the control network of dozens of large and medium-sized cities in China. The GPS automatic monitoring system for deformation of Geheyan dam in Qingjiang River, which he presided over and completed, played a key role in the severe struggle against the Yangtze River flood in 1998, and was praised by the relevant departments of the state.

In recent years, academician Liu Jingnan has won various awards for his research achievements, including one second prize and one third prize for national science and technology progress, and four first prizes for provincial and ministerial science and technology progress. He participated in the completion of the geodetic professional transformation system project and won the first prize of national excellent teaching achievements. During his tenure as vice president of Wuhan University in charge of scientific research, postgraduate and other work, he put forward the idea of running a school with discipline construction as the leader and scientific and technological innovation as the driving force to promote the leapfrog development of the University. Because of his outstanding achievements, he has won the titles of young and middle-aged experts with outstanding contributions from Hubei Province and the state and national excellent scientific and technological workers.
