Mobile satellite measurements on the Pomeranian Metropolitan Railway

This paper presents the process of organization and execution of the mobile satellite measurements conducted on the tracks of the Pomeranian Metropolitan Railway before officially entry the line into operation. These measurements allowed for the accurate identification of the actual geometric shape of the line. In the paper the issues of both design and construction phase of this railway line has been described. Moreover, the geodetic works during implementation of the investment has been introduced. The analysis of the surveying results was focused on the issues like transformation the measured data to the local system of coordinates called Gdańsk '70, repeatability of measurement's results and comparison of measured route with the designed geometrical layout.
