摘要：

针对天基再入投送系统与传统星座轨道部署问题的不同，建立了用于轨道部署覆盖性能仿真的星下点轨迹、覆盖条带计算模型和覆盖判别条件模型；针对传统部署方法的不均匀性，提出了一种新的升力式再入飞行器全球部署方法。该方法采用双倾角条带覆盖方式克服了传统部署方法的固有缺陷,既实现了全球覆盖又提高了重点区域的覆盖重数。仿真结果表明该部署方法的覆盖性能相对传统方法有明显提高，在满足全球100%覆盖的同时又对重点区域的覆盖重数提高了约20%,覆盖性能优异。

Abstract:

In this paper，we focus on the difference between the deployment problems of the novel lifting reentry delivery system and the traditional constellation. The sub\|satellite point track model, the coverage band model and the coverage criterion model are established to simulate the performance of the orbit deployment. To conquer the limitation of the nonhomogeneity of the traditional deployment method, an improved double inclination band method is presented, and numerical simulations are carried out to justify its validity. The simulation result shows that the present method has a superior performance than the traditional one in that it both accomplishes the global coverage mission and enhances the coverage dimension of important area by about 20 percent.
