卫星通信（Satellite Communication）是指利用人造地球卫星作为中继站，实现地球表面或空间用户之间远距离信息传输的技术系统。其核心原理是通过卫星上的转发器接收、放大并转发来自地面站的信号，以覆盖广阔的地理区域。以下是卫星通信的详细解析：
卫星通信系统由三部分构成：
信号传输遵循“上行链路-卫星处理-下行链路”流程，典型延迟为250-300毫秒，符合国际电信联盟（ITU）《无线电规则》标准。
当前挑战包括频谱资源竞争、雨衰效应（Ku/Ka波段尤为显著）及高轨卫星延迟。最新进展聚焦：
卫星通信技术持续推动全球化信息互联，相关标准及案例可参考国际宇航科学院（IAA）发布的《卫星通信白皮书》及IEEE《航天器与卫星系统期刊》研究成果。
卫星通信（Satellite Communication）是指利用人造地球卫星作为中继站，在地面、空中或太空中的两个或多个终端之间传输信息的通信技术。以下是详细解释：
卫星通过接收地面站发射的无线电信号，经放大和频率转换后转发至目标接收端。整个过程依赖卫星的星载转发器和天线系统，信号传输路径涉及上行链路（地面→卫星）和下行链路（卫星→地面）。
低轨卫星星座（如Starlink、OneWeb）正通过大规模部署小型卫星降低延迟并提升带宽，未来或实现全球无缝高速互联网覆盖。
