In a first mode of operation, the navigation device provides position information based on a radio frequency navigation signals. If radio signals become unavailable, the navigation device enters a second mode of operation. In the second mode of operation the navigation device stores the most recent elevation and associates it with a reference elevation, the reference elevation is associated with an entry floor. The difference between a current elevation and the reference elevation is determined and this difference is divided by a floor height to obtain a floor number. The navigation device provides the floor number while reliable global position information is unavailable.
