| 摘 要： | 根据椭圆轨道的卫星通信链路中空间参数的变化规律，定义地心惯性坐标系下不同轨道两颗卫星的星际链路向量，建立椭圆轨道卫星星际链路数学模型，定义t时刻两卫星间星际链路可通的条件建立链路可见性数学判据。对于卫星通信系统的星座设计、组网、星载天线跟踪系统设计和多层卫星网络最优化路由搜索算法有参考价值。

| Abstract: | Based on the changing rule of various space parameters of elliptic orbit satellite communication links, through definition of inter-satellite link vector of two satellites on different orbits in geocentric inertial frame, the mathematic model of ellipse orbit inter-satellite link was established. The mathematic criterion of link visibility was also established based on the communication evaluation of inter-satellite links of two satellites under the moment T. The study was valuable for constellation design, networking, the design of satellite＇s antenna tracker system and the dynamic routing strategy in multi-layer satellite networks. |
