SYSTEMS AND METHODS TO EXTEND DEAD RECKONING USING WAYSIDE EQUIPMENT

A system to extend dead reckoning includes multiple input devices including primary input devices and secondary input devices, a location system configured to receive position information from the multiple input devices and to determine a location of a train, vehicle or car, the location system including a calculation module that is configured to, through operation of a processor, receive position information from the primary input devices, receive identification information from the secondary input devices and obtain position information of the secondary input devices based on the received identification information, and determine the location of the train with the position information of the primary input devices or determine the location of the train including dead reckoning with the position information of the secondary input devices when the primary input devices are unavailable or provide insufficient position information.
