The paper presents the problem satellite leveling of line structures using RTN (Real Time Networks) measurements referenced to ASG-EUPOS System. The possibility of the practical use of satellite leveling based on results of test measurement three sections of the railway with a total length of over 8 km. For the calculation of the normal height used the model of quasi-geoid "Leveling Geoid 2001" and a simplified linear interpolation. In the case of satellite RTN leveling method of calculating the normal height is less important. The most important factor is not sufficient ellipsoidal height determination accuracy of the RTN measurements, and their random nature of spread at the level of 9 cm.
