華為突然官宣,馬斯克始料未及,星鏈計劃或「夭折」?

华为作为在通信领域的巨头,手中掌握了数量庞大的专利,现在每个国家都在关注的5G领域中,华为手握的专利数量更是全球第一。目前华为的目标已经进一步确认,已经不仅仅是限制在地面上,目前华为官宣的一项专利显示出华为已经开始进军卫星通信领域了。

华为突然官宣,马斯克始料未及,星链计划或“夭折”?

星链计划成本极高,计划非常庞大

对于星链,大家都应该知道,这是马斯克公司成立的空间探索公司发起的一个项目,计划在五年内发射12000颗低地球轨道通信卫星,覆盖全球网络,目标的通信延迟仅为20微秒。

星链计划由于其多卫星复用和火箭技术而备受关注,但目前还远未达到星链的初始目标。

例如,在通信延迟方面,最佳结果只有42微秒,与20微秒的目标相差很大。

就卫星数量而言,这次是非常大的手笔,星链计划在五年内发射12000颗卫星,过去三年发射卫星的一共发射了刚超过20%的数量。

此外,发射的卫星也受到了一定程度的损害,要么是因为发射后失去了控制,要么是因为地磁风暴受损。

星链发射的49颗卫星,由于一场地磁风暴摧毁了40颗卫星,目前这个计划没有得到乐观的计划推进。

华为官宣,星链计划或“夭折”?

但最近,华为突然宣布了这样的消息,早在2020年,华为就申请了寻星专利,最近华为正式公开宣布了这件事情。

据了解,该专利可以帮助移动终端在低成本、低功耗的卫星通信中找到卫星。

华为突然官宣,马斯克始料未及,星链计划或“夭折”?

也就是说,未来智能手机将支持通过通信卫星连接到互联网,对于整个科技领域来说,也将是一大创举。

巧合的是,中国通信科学院近日宣布,与中信移动、中国卫通、华为、中兴通讯共同编制的《国际卫星无线电接口标准IMT-2020》报告主体部分已经完成。

简单地说,这一次,我国领导的第一个国际5G卫星无线电接口标准取得了重大进展。

也许很多朋友都不知道,星链其实采用依然还是4G标准,这就是为什么在定义目标延迟时,会以20微秒为标准,因为4G网络的延迟目标是20微秒。

华为突然官宣,马斯克始料未及,星链计划或“夭折”?

但现在问题出现了,卫星通信的5G标准正在制定中,这意味着星链计划在完成之前可能已经落后于当代的科学技术。

星链的计划完成之后,恐怕已经落后于时代

对于星链无法突破的网络延迟,目标是20微秒,而5G通信可以达到1微秒。显然,5G网络需要更好的网络速度。在速率上5G技术已经领先了4G非常多。

此外,如上所述,华为还拥有移动终端的寻星技术,然而使用星链网络需要以高昂的价格购买独立设备,约为3400万元人民币。

因此,在未来的市场竞争中,总的来说,星链将没有技术优势和成本优势,高昂的设备购买费用得到的反馈却可能是低于当前时代的速率体验。即网民所说的“低配高价”。

但问题远不止这些。星链计划发射的卫星寿命很短,只有5年左右,现在距离发射的第一批卫星发射已经过去了三年的时间,但只达到12000颗卫星目标的20%。

换言之,第一批卫星可能在达到目标之前就被废弃了,并以受控状态进入大气层并被烧毁。

华为突然官宣,马斯克始料未及,星链计划或“夭折”?

因此,我们不禁会怀疑马斯克的卫星是否会继续发射,如此高昂的成本是否值得继续发射剩余的卫星。

这是因为空间资源,特别是低轨道空间资源非常稀缺,而首先发射卫星的国家占据了这一位置。一旦位置被占领之后后续的卫星就必须另外找寻相应的轨道。

星链发射的卫星越多,以后的空间就越小。在空间资源方面,国际上的规则是先到先得,而目前科学研究表明在低地球轨道,它可容纳大约6万颗卫星。也就是说如果星链的所需要的卫星全部发射成功的话,将会用掉约20%的空间资源。

星链试图垄断,低轨卫星空间

据媒体报道,星链随后改进了其发射计划,把原来的12000颗卫星的数量增加到最多发射42000颗卫星,这显然是为了将低轨道空间转变为SpaceX的“私人领地”,因此几乎独一无二的卫星通信网络不再有竞争对手,如此极有可能会对需要低空轨道空间领域的项目造成垄断的局面

但也有一个转折点,因为星链需要地面站。如果恒星链想要垄断低轨道资源,恐怕它的地面站很难扩展到全球。所以,5G卫星通信还有机会,我们拭目以待。

对于华为进军卫星通信领域大家有什么看法,欢迎在评论区留下您的观点一起交流讨论。
