中文摘要：

该文对编队飞行小卫星的星间链路几何特性（方位角、仰角及星间距离）进行较为深入的研究。在提出椭圆轨道下编队小卫星星间链路几何特性的计算公式后，结合实例做了相应的仿真，并对仿真结果进行了进一步的讨论，得到了星间链路几何特性随轨道参数变化的规律。对于未来星座设计、编队小卫星组网等方面具有较大的参考价值。

英文摘要：

This paper focuses on the geometrical properties of Inter-Satellite Links （ISLs） of the small satellites formation flying under the elliptical orbits, including the azimuth, elevation and the distance. The article addresses the mathematical formula for these characteristics., and then presents the simulation results based on the given example. The paper also analyzes the law that the formation flying＇s ISL＇s geometrical characteristics change with the parameters of the satellite constellation. These results are important for future＇s constellation design, satellite networking, etc.
