Embodiment Construction
[0128] The main purpose of the present invention is to solve the problem that the conventional static calibration method does not consider the sensitivity of the fiber optic gyroscope zero bias to temperature, resulting in unsatisfactory error parameter calibration results, and to improve the Kalman filter, neural network filter, conventional LMS filter and other methods in the existing literature There are deficiencies in the accuracy, real-time, practicality, and dynamic input range of the random error processing of the fiber optic gyroscope. A complete, effective, high-precision and adaptable error processing process and method are proposed for the output signal of the fiber optic gyroscope component. It plays a very important role in improving the accuracy of inertial sensors and even the accuracy and performance of the entire inertial navigation system, and has guiding significance for the engineering application of fiber optic gyroscope components. In order to achieve thi...
