Due to the characteristic that the measurement error diverges with the distance increases, the train positioning method based on the odometriche sensor often needs to arrange more physical balise along the railway to achieve the convergence of the distance measurement error. The train positioning method based on satellite navigation system and electronic map can ensure the real-time convergence of distance measurement error, and can greatly reduce the laying of physical balise. While improving the real-time accuracy of train positioning, it reduces the labor of maintenance personnel in harsh environments. However, in the train positioning application of satellite navigation system, since only a straight-line distance can be calculated between two points, there is a large error in calculating the train position at the curved track. To solve this problem, this paper proposes a train positioning method based on satellite navigation system and electronic map. This method can calculate the precise position of the train at the curved track based on the information of the curved track, thereby solving the precise positioning of the train at the curved track.
