区域覆盖星座构型优化及协同控制策略研究

针对区域覆盖卫星星座的回归特性和构型维持需求,利用轨道半长轴和倾角与升交点赤经漂移和相位角漂移变化率之间的线性关系来优化星座构型参数,提高卫星星座构型的长期稳定性,同时通过协同控制轨道半长轴和倾角漂移量来实现区域覆盖星座构型维持。最后对区域覆盖天基雷达星座进行了构型优化设计和仿真,仿真结果表明了星座构型优化设计和维持策略的有效性。

Study on Configuration Optimization and Coordination Control Strategy for the Regional Coverage Satellite Constellation

In view of the regression characteristic and the configuration maintenance demand of the regional coverage satellite constellation,the constellation configuration is optimized using the linear relations between the semi-major axis and inclination and the rates of change of the ascending node right ascension and phase,which enhance the long-term stability of the satellite constellation configuration,simultaneously the sub-stellar and the phase are controlled through changing the deviations of the semi-major axis and the inclination.Finally the paper has carried the optimization design and the control simulation on the regional coverage space-based radar constellation,the simulation results indicate that the configuration optimization design and the maintenance strategy for the regional coverage satellite constellation are available and effective.
