摘要
多层卫星网络中卫星通信链路的空间几何参数研究,以三层网络中的ISL为对象,用类似于地面站对卫星方位角和仰角的定义描述星际链路的方位角、仰角,由此定义ISL的星际链路距离、仰角、方位角等空间几何参数。并采用可通性判断,统一各卫星通信链路空间几何参数的计算公式及多层卫星网络中相应空间参数几何特性。仿真结果证明,该计算方法可行。
The research of space geometric parameter of multi-layer satellite networks used the similar definition of geometric characters of the link from the earth station to satellite to describe space geometric parameter of the inter-satellite link in multi-layer satellite networks, taking the ISL of three-layer network for example, The communication evaluation was adopted to unify equations about space geometric characters of kinds of satellite communication links. The simulation results proved the feasibility of this method.
