The two coplanar elliptic-to-elliptic orbits transfer with two-impulse is considered in this paper. The problem is the rendezvous of two spacecrafts, and the target spacecraft is not fixed in its orbit, but keep moving as same as the tracing spacecraft. To solve the problem, the transfer time is computed using Lambertpsilas theorem and iterative algorithm. And improved genetic algorithm is also used...
