Abstract The application of GPS technology in Qinghai–Tibet railway mainly focuses on the navigation, monitoring, command, and dispatching system of the train positioning. GPS is used as the auxiliary train positioning device in the railway train control system of Qinghai–Tibet railway and is taken as a backup of the query balise (redundant system) in the moving block control system. The vehicle-mounted GPS shown in Fig. 3.1 is used as the auxiliary correction of the reference position of the ground track. GPS-aided dispatching system uses GPS to compute the actual positioning, the operational direction and speed of the operational train, and then transmits the positioning results to the dispatch center through wireless communication channel to realize the real-time whole-process monitoring and ensure the safety of the train. The continuous operational location information of train provided by GPS covers the whole operational line of the train (station and zone), which can be used to adjust the operation plan, train dispatching and controlling, and accurate real-time monitoring
