Starlink 星链


Starlink is a satellite constellation being constructed by SpaceX to provide satellite Internet access. The constellation will consist of thousands of mass-produced small satellites, working in combination with ground transceivers. SpaceX also plans to sell some of the satellites for military, scientific or exploratory purposes. Starlink constellation, phase 1, first orbital shell: 72 orbits with 22 each, 1,584 satellites at 550 km altitude. As of November 2019, SpaceX has deployed 122 satellites. They plan to deploy 60 more per Falcon 9 launch, with launches as often as every two weeks after late 2019. In total, nearly 12,000 satellites will be deployed by the late-2020s, with a possible later extension to 42,000. The initial 12,000 satellites are planned to orbit in three orbital shells: first placing approximately 1,600 in a 550-kilometer (340 mi)-altitude shell, then approximately 2,800 Ku- and Ka-band spectrum satellites at 1,150 km (710 mi) and approximately 7,500 V-band satellites at 340 km (210 mi). Commercial operation has begon in 2020.


首先在550千米轨道部署约1600颗卫星, 然后是在1150千米轨道部署约2800颗Ku波段和Ka波段卫星, 最后是在340千米轨道部署约7500颗V波段卫星。

“星链”始建于2018年2月22日,如果一切顺利, “星链”可以在全球范围内提供低成本的互联网连接服务。
