月亮强大的引力就像是地球的一个陀螺仪，保证了地球轴心的稳定性。
In some autotracking antenna systems of the mobile satellite communication earth stations, the laser gyroscope is used for tracking, which proves to have some disadvantages.
某些移动卫星通信天线自动跟踪系统采用激光陀螺进行跟踪，但激光陀螺跟踪有其不足之处。
The idea behind the experiment is simple: put a spinning gyroscope into orbit around the earth with the spin axis pointed toward some distant star as a fixed reference point .
实验背后的原理十分简单：将转动的回转仪放在环绕地球的轨道，转轴指向远处星体，作为固定基准点。
