Abstract

In this paper, recursive algorithm is presented for the simulation of the soft landing orbit of Chang'e-3, for making sure the location of the landing orbit and the perilune point. Recursive algorithm is a method of derivation from the state in a moment to the next moment through their relationship. Frist, the coordinate model of soft landing and the relevant parameters are set up. Second, the soft landing orbit of Chang'e-3 derivate by recursive algorithm. Third, the soft landing orbit and the perilune point are carried out after analyzing the result from the simulation. The simulation of the soft landing orbit shows that recursive algorithm is innovative in the simulation of orbit in high probability.
