为了扩大GEO卫星系统的覆盖范围,解决目前急需的极区通信问题,本文设计了大椭圆和地球同步轨道卫星的混合星座模型,对混合星座模型的覆盖和通信性能进行了仿真分析,实现了全球覆盖和极地与国土境内的连续通信,有效弥补了GEO星座的不足,研究结果对全球区域观测研究和通信星座设计有一定的参考价值。 In order to expand the coverage of the GEO satellite system and solve the polar communication problem, which is urgently needed, a hybrid constellation model of large elliptical and geosynchronous orbit satellites is designed. The coverage and communication performance of the hybrid constellation model is simulated and analyzed. Coverage and continuous communication between the Polar and the territory of the territory effectively make up for the deficiencies of the GEO constellation, and the research results have certain reference value for global regional observational research and communications constellation design.
