中国计划大规模扩展互联网卫星，已向联合国国际电信联盟（ITU）提交了超过20万颗卫星的计划，由新的CTC-1和CTC-2项目牵头，每个项目提议近10万颗卫星。此举正值北京批评埃隆·马斯克的SpaceX凭借其星链星座主导低地球轨道。控制宝贵轨道插槽和无线电频率的竞赛正在加剧。SpaceX目前拥有约1.5万颗已获批准的卫星（潜力可达3万颗），而中国旨在迅速赶上。这些申请凸显了北京建立自身在不断增长的太空互联网市场中地位的战略努力，可能挑战SpaceX目前的优势地位，并引发对轨道拥塞的担忧。

中国已申请发射20万颗卫星进入太空，此前曾因SpaceX的星链计划造成碰撞风险而受到批评。然而，专家们担心这一计划会加剧现有的太空碎片问题。拟议中的中国星座，如CTC-1，计划利用人口稠密的日地同步轨道（SSO）——一个已经容易发生碰撞的区域——增加 Kessler 综合症的风险，即碎片产生的连锁反应导致太空无法使用。与SpaceX不同，中国经常在轨道上废弃火箭级，从而增加了碎片场。虽然中国目前的卫星部署（国望136颗，广网/千帆108颗）落后于星链的9400颗活跃卫星，但计划规模巨大。担忧不仅限于碎片；大量的卫星数量可能会永久破坏夜空，影响观星。一些人推测，中国的动机也源于希望对抗像星链这样的技术，这些技术已被用于绕过互联网审查，如伊朗所见。

Chinese firms have signalled plans to launch more than 200,000 internet satellites, filing submissions with a UN agency just as Beijing accused Elon Musk’s SpaceX of crowding shared orbital resources.

A dozen or so submissions from various Chinese satellite players were filed with the International Telecommunication Union (ITU) at the end of last month.

The biggest projects – CTC-1 and CTC-2 – were for 96,714 satellites each and filed by the newly established Institute of Radio Spectrum Utilisation and Technological Innovation.

SpaceX launches another test flight of its mega Starship rocket

The institute was registered in China’s northern Hebei province on December 30, the day after it submitted its ITU filings, according to the Radio Association of China.

The United States and China have been racing to launch internet satellite megaconstellations in recent years, with the US-based SpaceX taking a big lead with its Starlink constellation, which accounts for most of the satellites in low Earth orbit.

But radio frequency bands and orbital slots in low Earth orbit are limited, and first movers for those resources can gain priority.

On Friday, the US Federal Communications Commission announced it had given SpaceX the green light to launch a further 7,500 second-generation Starlink satellites.

Those satellites must be in orbit by the end of 2031 and would bring SpaceX’s total to 15,000 satellites. Starlink has applied to the FCC to launch 30,000 satellites but a decision has been deferred on the rest.
