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。
In the multi-layer satellite network, the space geometric parameters of the satellite communication link are studied. The ISL in the three-layer network is used to describe the azimuth and elevation angles of the inter-satellite link in a similar way to the definition of the azimuth and elevation angles of the satellite by the ground station. Define the ISL’s inter-satellite link distance, elevation, azimuth and other spatial geometry parameters. The formulas for geometric parameters of the communication links in the satellite are unified and geometrical characteristics of the corresponding spatial parameters in the multi-layer satellite network are determined by using connectivity. Simulation results show that this method is feasible.
