Satellite internet is rapidly becoming a crucial component of global communication infrastructure, and its significance cannot be overstated. Firstly, it provides reliable, high-speed internet access to remote areas—such as mountains, oceans, and deserts—that are difficult or uneconomical for terrestrial networks to reach, thereby bridging the digital divide. Secondly, during natural disasters or emergencies that disrupt ground-based communications, satellite internet serves as a vital backup for emergency response and information dissemination. Moreover, with advancements in Low Earth Orbit (LEO) satellite technology—exemplified by systems like SpaceX’s Starlink and China’s “GW” constellation—latency has been dramatically reduced and bandwidth significantly increased, enabling demanding applications such as video conferencing, online education, and even telemedicine. From a national strategic perspective, developing independent and controllable satellite internet capabilities enhances a country’s competitiveness in space and strengthens its information security. Therefore, whether viewed through the lenses of public welfare, emergency resilience, or technological and national security strategy, satellite internet deserves serious attention.
卫星互联网正迅速成为全球通信基础设施的重要组成部分，其重要性不容忽视。首先，它能够覆盖传统地面网络难以触及的偏远地区，如高山、海洋和沙漠，为这些区域提供稳定、高速的互联网接入，弥合数字鸿沟。其次，在自然灾害或紧急事件导致地面通信中断时，卫星互联网可作为关键的应急通信手段，保障救援与信息传递。此外，随着低轨卫星（LEO）技术的发展，如SpaceX的Starlink和中国“星网”计划，卫星互联网的延迟大幅降低、带宽显著提升，已能支持视频会议、在线教育甚至远程医疗等高要求应用。从国家战略角度看，掌握自主可控的卫星互联网系统有助于提升国家在太空领域的竞争力和信息安全保障能力。因此，无论从民生服务、应急响应还是科技与安全战略层面，卫星互联网都值得高度重视。
