19 ABSTRACT In a method for determining the deviations of the actual position of a track (6) with respect to the desired position a first measuring unit (1), movable on the track, and a further second measuring unit (2) are placed at the two end points of a track section to be measured, and their positions as an actual track position are defined relative to track reference points (11). The second measuring unit (2) is moved in stages from a starting point in the direction of the first measuring unit (1) to the end point, wherein at every stop for implementing a measuring procedure, the measurement data of the actual track position are compared with the measurement data of the desired position and a corresponding differential value is calculated and stored. The position of the two measuring units relative to one another are determined in a coordinate system as a result of the reception of a position signal from surveying satellites. With each stop of the second measuring unit (2) - during its measurement movement in the direction of the first measuring unit (1) - the particular relative position change is obtained by the respective reception of a further position signal from surveying satellites.
