Job Resume

Li Jisheng was born in 1943 in Ji'nan City, Shandong Province. He graduated from Nanjing University's Department of Astronomy in 1966. Since then, he has served in the Xi'an Satellite Control Center (XSCC) and engaged in satellite dynamics research and satellite tracking, telemetry and control. From 1984 to 1986, he studied at the University of Texas at Austin in the United States as a visiting scholar. From 1988-1989, he developed satellite TT&C software with the French company, MATRA. In 1997, he was selected as a member of the Chinese Academy of Sciences. He is currently a standing member of the Science and Technology Committee of the General Equipment Headquarters. He is also currently an adjunct professor at Xi'an Jiaotong University.
He is a member of the Council of the Chinese Space Science and Technology Institute and an adviser of the TT&C Committee of the Chinese Astronautics Institute. He joined the American Earth Physics Society in 1986.

Academy and Scientific Findings

In 1992, he was recognized by the State Personnel Department as a "middle aged or young expert having made an outstanding contribution". In 1995, he won the China Space Fund Prize. In 2000, he received the Technology and Science Prize of the HLHL.
Li Jisheng is an expert in satellite orbit dynamics and satellite TT&C. Earlier, as a Chinese Space Science and Technology engineer, with his colleagues, he did his best to open up the field of satellite TT&C technology. He has made great contributions to the development of China's space program.
In the field of orbit dynamics, he developed "an orbit calculation method with the nodical period as integration step" which solved the "critical inclination" problem in orbit calculation for China's first retrievable satellite. Based upon the mechanism of Chinese low orbit satellite attitude control, he established the first perturbation force model for attitude control of three-axis stabilized satellites. In 1993, he set up the precision orbit determination system, which met the high precision requirements of China's new satellite and improved China's orbit determination capabilities so that they are now among the more advanced in the world. This system has become the primary method for orbit calculation of satellite TT&C missions.
Li Jisheng developed the principle of "modularized automatic scheduling" in designing and implementing satellite TT&C application software in 1978 and completed the software development for low orbit satellite TT&C missions.
This improved the standardization, applicability and automation of the software and has fundamentally changed the way that satellite TT&C application software is now developed. In 1984, he developed the software "DFH-2 TT&C scheduler and flight plan generator". It remedied defects causing low performance of the XSCC computer system and ensured the successful completion of the TT&C mission of the first Chinese geo-synchronous communications satellite "DFH-2".
Li Jisheng has been engaged in the research of satellite orbit dynamics and TT&C technology for over 30 years. He has won First-class Merit twice. He received one Second Prize for National Science and Technology Progress, two first prizes of ministerial level and nine second prizes. He has written two published books, one the monograph, "Satellite Precision Orbit Determination", and one the textbook "Space Vehicle Orbit Determination".
