Design and Implementation of Mini Inertial Measurement Unit of Fiber Optic Gyros

摘要

The design and implementation of Mini Inertial Measurement Unit (IMU) based on Fiber Optic Gyros (FOG) is presented, that is: integral structure including gyros, accelerometers and processing boards; sharing one light source and one digital signal processing unit for three-axis FOG. An JMU prototype was realized with a FOG performance of <0.5°/h bias stability and <100ppm scale factor accuracy.
