Detailed Documentation
This program implements a gyroscope random drift model based on AR (AutoRegressive) time series modeling. To address the random drift issue, we employ the Kalman filtering method - a widely adopted signal processing technique designed to filter noise and enhance signal precision. The implementation involves modeling the gyroscope drift as an AR process and applying Kalman filter recursion to estimate and compensate for the drift components. Key algorithmic steps include state-space formulation, prediction-correction cycles, and covariance matrix updates. Through experimental validation, we demonstrate that this approach effectively suppresses random drift and improves gyroscope measurement accuracy. Future research will explore additional methodologies such as adaptive filtering and machine learning techniques to further enhance gyroscope precision and robustness.
