FromWikepedia:

“Starlink is a satellite internet constellation operated by Starlink
Services, LLC, an international telecommunications provider that is a
wholly owned subsidiary of American aerospace company SpaceX,[4]
providing coverage to over 100 countries and territories. It also aims
to provide global mobile broadband.[5] Starlink has been instrumental to
SpaceX's growth.[6]

SpaceX started launching Starlink satellites in 2019. As of September
2024, the constellation consists of over 7,000 mass-produced small
satellites in low Earth orbit (LEO)[7] that communicate with designated
ground transceivers. Nearly 12,000 satellites are planned to be
deployed, with a possible later extension to 34,400.”

Eruopean Edition

The European Union is forging ahead with plans for a constellation of
internet satellites to rival Elon Musk-owned Starlink, after signing a
€10.6 billion ($11.1 billion) deal to launch nearly 300 satellites into
low- and medium-Earth orbits by 2030. The bloc wants the space tech to
boost its digital sovereignty by providing secure comms to governments.

First announced in 2022, Iris² (Infrastructure for Resilience,
Interconnectivity and Security by Satellite) is a public-private
partnership whose initial cost estimate (€6 billion) leapt 76% through a
fraught negotiation process. In the end, the program will be 61% funded
from the public purse; an industry consortium called SpaceRise, selected
in October, is making up the difference. This grouping includes French
satellite giant Eutelsat, which merged with European rival OneWeb back
in 2022.

”北京时间12月16日18时,我国在海南文昌卫星发射中心使用长征五号乙运载火箭,以一箭10星方式成功将卫星互联网低轨01组卫星发射升空,卫星顺利进入预定轨道,发射任务获得圆满成功。

这是中国星网的“国网(gw)星座”首次批量组网发射,也是第一次使用长征五号B执行卫星互联网发射任务。

卫星互联网低轨01组卫星使用Ka等频段载荷,主要为用户提供宽带通信、互联网接入等服务。

据悉,从中国星网向国际电信联盟第一次提交轨道频率申请看,首批要发射12992颗卫星。

国网星座是我国第一个巨型卫星互联网计划,也是我国首个空天一体6G互联网计划。

中国星网的“国网星座”星座包含两个子星座:gw-a59和gw-a2星座,形成覆盖全球的互联网卫星星座,未来将推出手机直连卫星通信模式。

gw星座共计规划发射12992颗卫星,其中gw-a59子星座6080颗,分布在500km以下的极低轨道;gw-a2子星座6912颗,分布在1145km的近地轨道。“
