Abstract:Given the heavy atmospheric density near the earth surface, the paper presents an ellipse parking orbit to help the satellite fleet through the debris layer of the at atmosphere and fit into the designed the orbit to fulfill tasks more efficiently when launching the satellite. In the mobile boundary point by solving the analytical solution and numerical solution contrastive method, reduce the computational difficulty. At last, based on a group of specific orbit parameters, the energy whit regard to the corresponding candidate point has been solved to testify the efficacy of the method proposed.
