Fiber optic gyroscope(FOG) is a kind of angular rate sensor based on Sagnac
erect with solid state, small size, light weight, wide dynamic range, fast starting,
low cost, high reliability and so on. Many countries pay much attention to FOG for
the military and civilian purposes. FOG is widely used in the world because of its
outstanding features. However, FOG is easily affected by the performance of its
components, parasitic effects and the surroundings. This leads to the FOG output
drift and deteriorates the precision of the inertial navigation system. Therefore, it is
significantly important to suppress the FOG drift error to improve the FOG
measurement accuracy.
