1 Introduction
Fiber optic inertial measurement unit is an inertial product developed for navigation and guidance, attitude measurement and control of small missiles and guided bombs, which is composed of three all-solid-state fiber optic gyroscope instruments, three quartz accelerometers and data packing board, etc. It measures the angular velocity and linear acceleration of carrier movement, and provides information for carrier attitude and navigation control. The measurement results are output via RS422 serial port.
