In this paper, the possibility of using an accelerometer-gyroscope based inertial sensor to improve a train locating system based on satellite navigation is described. Disadvantages of the inertial sensors are introduced as well as the calculation of desired data and their filtration. A poly-phase filter design is described as a possible solution for distortion elimination. A design approach of a prototype device which implements the inertial measurement and filtration is also described. The device is equipped with four sensors and it is connectable with a common PC by using USB. The software interface is suited for usage with LabVIEW software.
