| 摘 要： | 对用低轨子星座和椭圆轨道子星座组成的混合卫星星座实现不均匀覆盖进行了研究。给出了低圆轨道和椭圆轨道的设计方法和计算模型。基于对传统粒子群算法的改进,提出了一种自适应变异与非线性单纯形法综合的高效粒子群优化算法对星座进行优化设计,并给出了设计的某混合卫星星座的整体构型。分析结果表明:该法明显优于遗传算法和传统粒子群算法。

| Abstract: | The non-uniform coverage of satellite constellation to the earth using a hybrid constellation formed by one low earth orbit(LEO) child-constellation and one elliptic orbit child-constellation was studied in this paper.The method of designing LEO and elliptic orbit was expounded,and the calculation formulas were offered.An optimal design of effective particle swarm algorithm(AHPSO) within the integration of adaptive mutate and the nonlinear simplex method was put forward.The configuration of hybrid constella... |
