Hansen Coefficients in Satellite Orbital Dynamics

Prof. Lianda WU worked in Purple Mountain Observatory, Chinese Academy of Sciences (CAS). As a member of the Astronomical Committee, CAS, he successively served as the leader of Astrometry and Celestial Mechanics Branch, Chief Researcher of the Innovation Team, and Director of the Center of Artificial Satellite Observation and Research. He has dedicated to the research of satellite dynamics and achieved significantly on orbit determination, perturbation calculation, data processing, and detection methods of space debris.

Dr. Mingjiang Zhang received his Ph.D. in Astrometry and Celestial Mechanics from the University of Chinese Academy of Sciences. He is currently a Project Researcher in the Department of Applied celestial mechanics and Space Object & Debris Research, Purple Mountain Observatory, Chinese Academy of Sciences. His research focuses on satellite dynamics, analytical mechanics and orbit data processing and application.
