Optimal Design of Regional Coverage Common-track Satellite Constellation via Genetic Algorithm

讨论了使用MATLAB的遗传算法工具箱GATOOL进行区域覆盖共地面轨迹卫星星座的优化设计方法。介绍了共地面轨迹卫星星座的参数特性,讨论了使用遗传算法工具箱GATOOL进行区域覆盖共地面轨迹卫星星座优化设计的方法,针对中国区域进行了仿真设计。仿真结果表明,该类型星座能够以较少数量的卫星为我国提供良好的覆盖性能,适于我国的区域覆盖卫星通信系统采用。

The optimal design method for regional coverage common-track satellite constellation based on Genetic Algorithm Toolkit （GATOOL） of MATLAB was proposed. The parametric characteristics of the common-track constellation were analyzed. The optimal design method based on GATOOL was studied and some optimal constellation schemes for China were proposed. Simulation results show that the optimal common-track constellation can provide favorable coverage performance to China with fewer satellites, and hence is appropriate for the regional coverage satellite system of China.
