近日，中国向国际电信联盟（ITU）提交了超过20万颗新卫星的轨道与频率使用申请，引发全球关注。这一大规模申请主要服务于国家正在推进的低轨宽带卫星互联网星座计划，旨在构建覆盖全球、自主可控的天地一体化通信网络。此举不仅体现了中国在航天和通信技术领域的快速进步，也反映出其在全球卫星资源竞争中的战略布局。随着星链（Starlink）、一网（OneWeb）等国外巨型星座加速部署，各国对有限的近地轨道和频谱资源争夺日益激烈。中国此次集中申报，既是对未来通信基础设施的前瞻性布局，也是保障国家空间权益的重要举措。不过，实际发射数量将根据技术发展、市场需求及国际合作情况逐步推进，并非所有申请卫星都会最终入轨。专家指出，如此庞大的星座计划还需解决空间碎片管理、轨道协调与可持续利用等挑战。
Recently, China submitted applications to the International Telecommunication Union (ITU) for over 200,000 new satellites, seeking rights to specific orbital slots and radio frequencies—a move that has drawn global attention. This large-scale filing primarily supports China’s national low-Earth orbit (LEO) broadband satellite internet constellation initiative, aiming to build a globally covered, independently controlled space-ground integrated communication network. The move reflects both China’s rapid advancement in aerospace and telecommunications technologies and its strategic positioning in the global competition for satellite resources. As foreign mega-constellations like Starlink and OneWeb accelerate deployment, international competition for limited LEO slots and spectrum resources intensifies. China’s coordinated filing represents a forward-looking infrastructure strategy and a key step to safeguarding its space-based interests. However, not all proposed satellites will necessarily be launched; actual deployment will depend on technological readiness, market demand, and international cooperation. Experts note that such an ambitious constellation also faces challenges including space debris mitigation, orbital coordination, and sustainable use of space resources.
