Abstract

The accuracy and reliability of train positioning are crucial for ensuring safe train operation. Currently, inertial navigation systems are widely used in various autonomous navigation fields. However, inertial navigation suffers from the problem of error divergence over time. Therefore, to compensate for the drawbacks of inertial navigation systems, combined navigation has become a development trend in inertial navigation technology. Combined navigation using inertial navigation and laser velocimetry is a high-precision positioning solution. However, it still faces the challenge of error accumulation. Considering the requirements of real-time performance, high precision, and immunity to external environmental interference in train positioning, this paper introduces geomagnetic navigation into the combination of inertial navigation and laser velocimetry. This approach aims to solve the problem of error accumulation and further improve the accuracy of combined navigation. The proposed method is validated through onboard combined navigation experiments.
