Abstract

At present, the commonly used Angular Rate Gyro components on aircraft are mostly Liquid Floating Gyroscopes, but the disadvantages of locked rotor caused by the wear of its bearings and rotors are gradually exposed in long flight. In contrast, Fiber Optic Gyroscope (FOG) has the advantages of wide dynamic range, wide measurement range, less affected by vibration and impact, fast start-up and long service life. In order to realize the use of fog components in aircraft, this paper analyzes the main error sources affecting the accuracy of fog by modeling the fog components. Finally, according to the main characteristics of fog changing with temperature, it is proposed that the error can be reduced by Least Squares - Support Vector Machine method.
