在400公里高的轨道上，不推进的话，卫星的轨道寿命通常是几个月，200公里高度的轨道寿命是几周。
At 400 kilometers, orbital lifetimes are usually measured in a few months without re-boost. At 200 kilometers this drops to a few weeks.
该卫星将被定位于经过验证的1300公里的太空轨道上，将能够提供各种广泛的应用，使其设计服务寿命能长达15年以上。
The satellite will be based on the space-proven 1300 platform, which has the flexibility to support a broad range of applications, and is designed to provide service for 15 years or more.
卫星在轨道上的寿命从几天到几百年不等。
Satellite lifetimes in orbit range from a matter of days to hundreds of years.
当卫星的使用寿命结束后，它们常常会被定位到遥远的轨道，不太可能危及正在工作的卫星。
When satellites reach the end of their useful lives they often are parked in remote orbits where they are unlikely to endanger working satellites.
