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.
