<p>The present invention relates to a method for determining a position of a navigation device (100). The navigation device (100) is adapted to determine a position of the navigation device (100) based on a plurality of different positioning procedures (301-304). Each positioning procedure (301-304) is working with a predefined parameter set. A plurality of geographical areas (A-C) is provided and each geographical area (A-C) is associated with one of the positioning procedures (301-304). An approximate position of the navigation device (100) is determined and based on this approximate position a geographical area (A-C), in which the navigation device (100) is located, is determined. Base on the determined geographical area (A-C) one of the plurality of positioning procedures (301-304) is selected, and based on the selected positioning procedure (301-304) the position of the navigation device (100) is determined.</p> |
