中国首颗大容量通信卫星成功发射 高铁上网将提速

今天(12号)19时04分,我国在西昌卫星发射中心成功发射实践十三号卫星,这次发射任务也是长征系列运载火箭的第246次发射。
实践十三号卫星是我国首颗高通量通信卫星,也是我国技术试验和示范应用成功结合的典范,对于促进我国通信卫星技术及产业的跨越发展具有重要里程碑意义。
实践十三号卫星是东方红三号B平台全配置首发星,设计寿命15年。卫星突破了电推进、Ka通信载荷、高轨激光通信等制约我国航天技术跨越发展的一系列关键技术,将在轨实现东方红三号B平台功能和性能指标考核,开展我国宽带多媒体卫星通信系统业务试验,探索星地双向高速激光通信技术及应用。
实践十三号卫星创造了我国通信卫星多个“首次”:首次在高轨卫星工程化应用自主研制的电推进系统,完成南北位保任务,大幅提高有效载荷装载比和卫星在轨寿命;首次在我国卫星上应用Ka频段多波束宽带通信载荷,通信总容量达20Gbps,超过我国已研制发射的通信卫星容量总和;首次开展我国高轨卫星与地面的双向激光通信技术试验,速率最高达到2.4Gbps;首次在我国高轨长寿命通信卫星上百分之百工程化应用国产化产品,改变了相关产品长期依赖进口的局面。
实践十三号卫星完成试验验证后,将转入Ka频段宽带通信试验业务,纳入“中星”卫星系列,命名为中星十六号卫星,使我国成为继美、欧等少数发达国家后掌握Ka频段宽带通信这一先进技术的国家,可为我国通信设施不发达地区的用户提供优良宽带服务,促进宽带卫星通信在高铁、船舶、飞机等移动载体以及企业联网、应急通信等领域的应用。(央视)
#焦点直击# 【发卫星!“超级空中路由器” 实践十三号发射 飞机高铁都能有宽带信号】我国首颗高通量通信卫星——实践十三号卫星4月12日19时04分在西昌卫星发射中心成功发射。它的通信总容量超过了之前我国研制的所有通信卫星容量的总和,被誉为“超级空中路由器”。这颗卫星不受地面条件的限制,可为偏远地区,移动中的飞机、高铁、车辆、轮船等提供优良的宽带信号服务。卫星厉害,火箭也厉害。这次发射用的是长征三号乙运载火箭,这是长征系列运载火箭的第246次发射。
另据新华视点:
【实践十三号卫星发射成功】今晚19时04分 ,实践十三号卫星在西昌卫星发射中心升空。这是我国迄今通信容量最大的宽带卫星,也是国内首个应用电推进技术的卫星,同时也是东方红三号B平台全配置首发星,设计寿命15年,创下国内通信卫星技术的多个“首次”,将使我国通信卫星能力实现重大跨越。

可喜可贺。大容量通信卫星的发射,以后屁民也可以享受高速的网上冲浪。只要不被那些大集团当垄断的工具就好了,高速上网也要成为普惠福利就好了。
