卫星互联网,还未走出“大哥大困境”
Hu Xiu· 2025-09-28 13:32
9月24日傍晚时分,山东日照,运载火箭底部喷薄而出的橘红色火焰瞬间照亮了海面,远处海滩上的观众纷纷按下快门。火箭缓缓上升,随后加速冲向太 空,将12颗低轨卫星送入距离地面600公里的LEO轨道。 这是我国卫星产业尤其是低轨星座加速发展的缩影。但是,新的烦恼、新的挑战也不可避免地到来。一方面是商业困境,在本周举行的2025中国无线电 大会上,业内专家称"今天的卫星通信还没有走出1G时代'大哥大'的困局",没有形成规模经济,建议全力发展5G/6G NTN(非地面网络),积极探索星地 网络的协同组网和运营。 另一方面,大型低轨星座发展带来的太空交通和频轨资源管理挑战日益严峻,轨道运行安全与空间避碰问题已无法回避,但目前仍缺乏太空交通的管理 规则,而且国内外对于卫星态势感知平台数据的共享仍不畅通。 从供给侧来看,火箭发射、集成电路、卫星制造和通信技术的进步,加速推动卫星产业快速发展。比如在卫星制造方面,卫星小型化、模块化、组件化 已成为可能,进一步降低了成本,缩短了研制周期。从通信技术来看,调制与编码技术、多天线波束赋形技术能力快速发展,而且基于毫米波、太赫 兹、激光通信等星际链路技术也逐步成熟。 从需求侧来看,地震 ...
