Distance dimensions in a predetermined spatial region of a reference map are corrected during positioning of an object from which dimensions the object position is determined from a satellite signal, received via a receiving unit at the location of the object, representing the distance from the satellite to the object. The distance dimensions are determined form received satellite signals using a satellite-supported receiver unit in a plurality of locations of an object in the predetermined spatial region. Using a predetermined object position, which can be known in advance or estimated, distance dimension which corresponds to the predetermined object position are back-calculated by incorporating the satellite positions of the satellites from which the satellite signals are received. Based on the difference between the respectively determined and back-calculated distance dimensions, a correction for at least part of the predetermined spatial region around the specified object position is stored and/or updated.
