双层卫星网络中MEO与LEO卫星连接度分析
Analysis of Connected-Degree in MEO/LEO Double Layer Satellite Networks
【摘要】 分析了在星座结构参数确定的条件下,中轨道/低轨道(MEO/LEO)双层卫星网络弱连接模型中层间连接度参数的选取。给出了连接度的理论分析和仿真结果,证明了在MEO/LEO双层卫星网络中,MEO卫星不应与其视距范围内的所有LEO卫星建立星间链路连接,而须根据MEO和LEO卫星间仰角等参数作出合理选择。
【Abstract】 The selection of connected degree of MEO satellite and LEO satellite in MEO/LEO double layer satellite networks under certain constellation parameters was analyzed in this paper. In MEO/LEO double layer satellite networks, the inter-satellite link of MEO/LEO satellite should selectively established according to the elevation angle and other parameters not the in-line principle.
