Research of the orbit programming for on-orbit emergency service with multi-constraint

The orbit programming for on-orbit emergency service is studied in this paper. The problem is considered under multi-constraint such as finite thrust and limited service time. The optimal object is to minimize the cost of orbit transfer. It is a nonlinear optimization problem with multi-constraint. A general optimization model is set up for multi-impulse, multi-revolution rendezvous which the impulse applied at apogee or perigee of the transfer orbit. A numerical example is given. The solutions show that this kind of problem can be solved by the strategy prospered in this paper.
