Real-Time Calibration of FOG´s Scale Factor Basic on Regression Analysis

In the application process of fiber optic gyroscope (FOG), scale factor will have the drift when the environment changes. the drift will make a big error on the measurement results, therefore real-time calibration method in scale factor of FOG is necessary. the traditional calibration method is too inconvenient to behave, so the purpose of this paper is using the regression analysis to accurately estimate the scale factor of FOG, and achieving real-time calibration.
