Abstract	This project was to investigate the use of microelectromechanical (MEM) arrays, combined with GPS, to provide the location of locomotives with sufficient accuracy for communications based train control systems. A laboratory prototype system was designed, fabricated, and tested, navigation and Kalman filter algorithms developed and tested, and the code for these algorithms developed. Field testing of the prototype system was conducted on Amtrak and the rest data analyzed. Final revisions to the system, including debugging the navigation and Kalman filter software, were completed. The prototype system proved to be sufficiently successful that a follow-on contract was awarded to design, build, and test a production prototype of this system suitable for use with Positive Train Control systems.
