Abstract :
We explore the integration of different sensor data in a multifilter, multisensor architecture for an onboard train navigation system. GPS, Doppler radar, track-based balises (or beacons) and gyros are the sensors used. The performance of stand-alone sensors is compared with their integration in pairs when a train is simulated over a track trajectory. Improvements in position fixing accuracy are highlighted and further benefits in recalibration of on-board systems are suggested when use is made of fixed balises
