Aircraft Flight Control Fiber Optic Gyroscope GPS Position And Orientation System
Employing high accuracy FOG, Q-flex accelerometers, dual-frequency GPS position & orientation system, barometric altimeter and advanced integration navigation and attitude measurement algorithm, the performance of Attitude and Azimuth Integrated Navigation Fiber Optic Vertical Gyro has been dramatically improved. Combining built-in high accuracy IMU (inertial measurement unit) with satellite, it could output high accuracy position, speed, attitude, angular speed and acceleration information. While the satellite signal is completely covered, system would enter into pure inertial mode. By use of high accuracy FOG, it could still keep good attitude measurement accuracy in certain time. Integrated with barometric altimeter, it could make correction and get higher accuracy height information.
Application
Aircraft flight control and navigation
Ship-borne & vehicle-borne navigation system
