UTILIZATION OF FIBER OPTIC GYROS IN INERTIAL MEASUREMENT UNITS

The core of today's inertial navigation, guidance and control (pointing) systems, including those for ships, is an inertial measurement unit (IMU) consisting of gyro sensors, accelerometer sensors and a processor unit. Fiber optic gyros have now been developed to the point where they are being introduced into advanced engineering models of the next generation of IMUs. The operating principles of the interferometric type of fiber optic gyroscopes are explained, and are compared with those of ring-laser gyroscopes. Test data are presented, and the unique characteristics of the fiber optic gyro are discussed with special emphasis on the role they will play in fault-tolerant IMUs of the future.
