Abstract: According to the development trend of the next-generation train operation control system, the Qinghai-Tibet Railway train control system replaces a large number of balise deployed in the section by adopting a real-time train positioning solution based on satellite positioning system. The deployment of this system can reduce the deployment and operation costs of Qinghai-Tibet Railway. At the same time, service of real-time accurate positioning of trains can be provided. This paper analyzes the satellite positioning scheme, and proposes the combination of the on-board speed and distance measurement information when the satellite positioning system is used for continuous train positioning. In this way, the problem of positioning the train at the wrong track can be avoided when the train passes through the switch.

Key words: Qinghai-Tibet Railway, train operation control system, on-board electronic map, satellite positioning
