| 摘 要： | LEO/MEO双层卫星星座是现代卫星通信系统星座研究的热点。运用理论分析的方法,对LEO/MEO双层卫星星座层间链路的链路距离、仰角、方位角等几何参数进行了研究,给出了各自的计算公式,并进行仿真分析。通过仿真发现,层间链路几何参数变化的突出特点是变化范围大、变化剧烈且周期性不明显。

| Abstract: | The LEO/MEO satellite constellation is the research focus of modern satellite communication system. The geometric characteristics of inter-layer ISL, including distance, elevation angle and azimuth angle, are analyzed in this paper using theory method. Their calculating formulas are presented and the simulation is performed. The simulation results show that the primary geometric characteristics of inter-layer ISL are wide variation range, acute variation and indistinct periodicity. |
