In the paper the essential assumptions regarding a research project implemented by a consortium of Gdansk University of Technology and Gdynia Maritime University are presented. The project has been commissioned by National Center of Research and Development with cooperation with Polish Railways (PKP Polskie Linie Kolejowe S.A.). The project is focused in implementation of modern measurement techniques using Global Navigation Positioning System GNSS, Inertial Navigation System INS and Mobile Laser Scanning MLS in a railway network management process. The precise aim of the research is both determine geometric parameters of a railway geometric layout as well as a railway vehicle movement trajectory. For this reason the innovative technique of mobile satellite measurements will be used. In the paper a synthetic description of the project together with the particular stages are presented. Also, a part of research which was realized in 2018 is shown. In the first stage, Gdansk University of Technology made a research of existing common methods for determining and assessing a track alignment, presented an idea of mobile investigation of track axis by the use of satellite measurements, took into consideration an issue of influence of dynamic behavior of the measurement vehicle on the accuracy of determined track positions by the use of GNSS/INS techniques and finally presented a technical project of measurement platform. Gdynia Maritime University made a query of GNSS/INS/MLS in measurements of track alignment, elaborated a scheme of measurement devices placement on the mobile measurement platform and studied possibilities of increasing accuracy for estimation a railway vehicle localization in relation to common techniques used by polish train operators.
