摘　　要：分析一种全球导航星座的星间链路，得到了星间距离、俯仰角、方位角等参数的变化曲线。最后，通过对这些空间参数的变化曲线进行分析，对星间链路的天线设计提出了基本要求。The changing of range, elevation and azimuth are obtained based on analysis of the inter-satellite links of a navigation satellite system. Following this, basic requirements on design of the antenna systems are proposed for the inter-satellite links through analysis of the change curve of these spatial parameters.
