Study on nonlinear error calibration of fiber optical gyroscope scale factor based on LSTM

•The coupling effect of input velocity and temperature is considered.•A new fast calibration method is established.•LSTM is used to comepensation the nonlinear error.•The calibration time is shortened by 30% while the angle measurement error is reduced by 70%. The calibration accuracy of the inertia...
