Barometers measure pressure. And knowing the pressure at your location(assuming its atmospheric pressure and that U are not in a sealed chamber) one can calculate the altitude(mean height above sea-level). This further improves the accuracy of your location when using GPS to calculate Latitude and Longitude.
