从空间提供的连接是实现真正和不间断的全球覆盖的最终方法，目前有几个大型卫星星座正在进行快速部署。这封信为在如此密集的卫星网络中建立下行链路覆盖概率模型提供了一种易于处理的分析方法。该框架利用随机几何中的工具，利用卫星对地路径损耗建模和视距概率公式的最新发展。仿真结果表明，即使在卫星数目较少的情况下，也能很好地符合所给出的解析形式，这表明系统设计者可以利用所获得的见解来分析预测和优化预期的下行链路覆盖性能。
Connectivity provided from space is the ultimate method for a true and uninterrupted global coverage, where there are several massive satellite constellations that are currently undergoing rapid deployment. This letter lays a tractable analytic approach for modeling the downlink coverage probability in such dense satellite networks. The presented framework utilizes tools from stochastic geometry leveraging recent developments in Satellite-to-Ground path-loss modeling, and in Line-of-Sight probability formulation. Simulation results show a very good match to the presented analytic forms even for lower number of satellites, suggesting that the obtained insights can be used by system designers to analytically predict and optimize the expected downlink coverage performance.
