Abstract

This paper discussed the problems in the soft landing of Chang'e-3 Probe on moon, established a Selenocentric celestial coordinate system, used the latitude and longitude coordinates coefficients conversion formula, calculated the location of the perilune and the apolune of Chang'e-3 soft landing. The author divided the landing process into five stages: main decelerating phase, fast adjustment phase, crude avoidance phase, fine avoidance stage and free fall process. By using Newton movement theory and the conservation of energy, the author calculated the speed of Chang'e-3 at the perilune and the apolune, and then deduce the relationship of the above speed with the long radius and short radius of moon. The research in this paper makes preparation for further research into the implementation of landing.
