Summary:A method for determining the altitude profile of a section of track for a rail vehicle has the following method steps: acquiring position data and altitude data by means of a receiver, installed in the rail vehicle, of a global navigation satellite system (GNSS) when the section of track is travelled along at least once; increasing the accuracy of the altitude data obtained by means of the GNSS by determination of the carrier phase of the signals of the navigation satellite or satellites; increasing the accuracy of the altitude data which are obtained by means of the GNSS by differential correction of the altitude data with the aid of an RTK network; and calculating the variation in the altitude profile of the section of track by processing of the position data and altitude data acquired in the preceding steps.
