1. A method for determining correction values for a position correction of a track, with the steps
recording an actual geometry of a track section using an inertial measurement device arranged on a track inspection vehicle while the track is being travelled on,
outputting measuring data of the recorded track section by the inertial measurement device to an evaluation device,
simulating a virtual inertial measurement of the same track section with a target geometry using a simulation device to obtain simulated measuring data for the target geometry, and
determining the correction values for the position of the track by subtracting the simulated measuring data from the measuring data of the inertial measurement device using a computing unit.
