TRACK IRREGULARITY MEASUREMENT USING AN INS-GPS INTEGRATION TECHNIQUE

The knowledge of geometric track irregularities that are dangerous to dynamic safety (DYSAF) of railways becomes evident with rising use of tilting trains like the German ICE3 or ICT, as irregularities may lead to train derailment. To identify track defects, a new measuring technique using a differential global positioning system (DGPS) and an inertial navigation system (INS) to determine the position of the track measuring system is presented. The paper discusses the system design and integration technique and presents experimental results from the laboratory test vehicle. It also outlines critical aspects of high-precision DGPS/INS integration.
