联邦通信委员会批准在低轨道运行的spacex 1584互联网卫星

    网易技术新闻,4月28日,来自外国媒体的报道,联邦通信委员会(FCC)最近批准了SpaceX的请求,允许该公司在原计划以下的轨道上发射大量未来的互联网卫星。SpaceX将于下个月在佛罗里达州正式发射其第一颗互联网卫星,而FCC的批准意味着其星链项目的主要监管障碍已经消除。去年11月,SpaceX向联邦通信委员会提交了一份请求,要求对StarLink项目计划进行部分修订。根据SpaceX最初的计划,该公司被允许将4425颗互联网卫星发射到距地面1110至1325公里的轨道上。但是,在丁丁A号和丁丁B号测试卫星发射后,SpaceX决定将其中1584颗送入离地面约550公里的低轨道。SpaceX总裁Gwynne Shotwell在一份声明中说:“这一批准突显了联邦通信委员会对SpaceX部署互联网卫星计划的信心。该计划将为全球用户提供可靠和廉价的宽带服务。spacex认为,通过在该轨道上运行卫星,将大大减少星链项目的信号延迟,传输时间将缩短到15毫秒。较低的轨道也意味着信号覆盖将比原计划少16颗卫星。SpaceX还表示,这一变化将有助于减少空间碎片。在550公里的高度上,卫星受地球大气的影响更大,脱离轨道的速度比高轨道卫星快得多。因此,如果任何一颗“星链”卫星不能运行,它将在脱离轨道后不久在大气中燃烧。然而,并不是每个人都满意SpaceX的最新计划。另一家公司,开发大型卫星互联网网络的OneWeb,和卫星运营商开普勒通信公司,对SpaceX的变更请求提出了申请。因为spacex使用相似的频率,如果星链计划被移到较低的轨道上,他们的卫星可能会被破坏。但最终,联邦通信委员会认为不会有干扰问题。SpaceX计划于5月从佛罗里达州卡纳维拉尔角发射第一颗恒星链卫星。(韩冰)
