FIELD: transport.
SUBSTANCE: invention relates to positioning of railway vehicles. Proposed system comprises satellite navigation system station connected to differential correction computer, data acquisition and processing unit including processor connected to data base and gateway, positioning unit including controller connected to memory unit of the station digital models and data base, computer-aided workstation and navigation communication hardware installed at moving objects. Every navigation device comprises navigation signal receiver, GSM/GPRS radio station with Wi-Fi adapter, slots for two sim-cards, inertial navigation system unit, controller two plug-in memory units and microprocessor. Besides, it includes onboard train motion controller and data transmission circuit. GSM/GPRS radio station is connected via GSM/GPRS circuit in TCP/IP protocol to data acquisition and processing unit.
EFFECT: higher accuracy and validity of location.
