| 摘要: |
| This paper addresses the challenge of accurately and timely determining the position of a train, with specific consideration
given to the integration of the global navigation satellite system (GNSS) and inertial navigation system (INS). To overcome
the increasing errors in the INS during interruptions in GNSS signals, as well as the uncertainty associated with process and
measurement noise, a deep learning-based method for train positioning is proposed. This method combines convolutional
neural networks (CNN), long short-term memory (LSTM), and the invariant extended Kalman filter (IEKF) to enhance the
perception of train positions. It effectively handles GNSS signal interruptions and mitigates the impact of noise. Experimental
evaluation and comparisons with existing approaches are provided to illustrate the effectiveness and robustness of the proposed
method. |
