| Abstract: |
| Based on the analysis of the MEO(Medium Earth Orbit） orbit for navigation satellites, a design method of MEO lunching direct injection with upper stage is proposed, and orbital dynamic equation and iterative calculations model are built. For sending more payloads into orbit, the key factors that affect launching capability are analyzed, and the objective optimization model based on adaptive genetic algorithm is established for optimizing launching trajectory. A numerical simulation proves the validity of the design method and optimization method. The result shows that the optimization method is favorable for increasing launching capability. |
