摘要
光纤陀螺可测量沿其轴向转动角速度,利用此功能通过四位置法可以实现寻北、实验室所在纬度以及地球自转角速度的测量.本文介绍光纤陀螺寻北仪和四位置法的工作原理.另外还介绍了寻北仪的实验装置和基本操作过程,以及对数据的处理方法.
Fiber-optic gyroscope （FOG） can be used to measure the velocity of rotation on its axis. Using this method and four-position scheme, we measure the north of the earth, the latitude of laboratory and the speed of self-rotation of the earth. The main principles of FOG north seeker and four-position scheme are introduced. The experimental equipment of north seeker, experimental steps and the data treatment method are also discussed.
