摘　　要：在研究卫星失效情况对低轨星座覆盖性能的影响。随着低轨卫星星座在全球通信和导航中的应用日益广泛,研究其在不同失效情况下的覆盖性能对于确保系统稳定性和服务质量具有重要意义。本文首先介绍了“星链”星座的基本情况,并基于覆盖性能指标对其进行初步分析。随后,基于STK与MATLAB仿真软件,对星座在不同数量卫星失效情况下的覆盖性能进行了仿真与分析。结果表明,不同数量的卫星失效对星座的覆盖性能有显著影响。This paper aims to study the impact of satellite failures on the coverage performance of low Earth orbit(LEO)constellations.With the increasing application of LEO satellite constellations in global communication and navigation,investigating their coverage performance under various failure scenarios is of great significance for ensuring system stability and service quality.The paper first introduces the basic information of the“Starlink”constellation and conducts a preliminary analysis based on coverage performance indicators.Subsequently,using STK and MATLAB simulation software,the coverage performance of the constellation under different numbers of satellite failures is simulated and analyzed.The results show that different numbers of satellite failures have a significant impact on the coverage performance of the constellation.
