地球同步轨道保持 earth stationary orbital keeping
- 太空之梯的主体平台将会被放在卫星全天环绕地球且保持在同一点上空的同步轨道上——或称之为克拉克轨道。
The main platform for the space eleator would hae to be placed in the geosynchronous or "Clarke" orbit where satellites take 24 hours to orbit the Earth, and thereby hoer aboe the same point on the ground.
