English abstract:
Using pedestrian navigation and guidance services in indoor areas, a challenging task is to determine the correct floor of a user in a multi-storey building as most common indoor location techniques provide only 2-D position determination. In this case it can be recommended to augment the position determination system with a barometric pressure sensor for direct observation of height differences. In the research project NAVIO (Pedestrian Navigation Systems in Combined Indoor/Outdoor Environements) tests with different sensors have been performed and their results are presented in the paper. The tests show that it is possible to determine the correct floor of a user using a barometric pressure sensor as the standard deviation of the estimation of the height differences is better than  1 m.
