Location has become one of the most relevant context parameters for mobile applications. Technology for the positiong such as Global Positioning System (GPS) has been widely adopted for locating the mobile user. However, for mobile applications that use an off the shelf GPS-receiver such as a PCMCIA card attached to a PDA, the correctness of the positioning is yet unsatisfying. Especially pedestrians, walking in urban areas, may experience strong deviations of the detected position from their actual position. In this paper, we present our approach to provide a software-based solution for a more correct position to a mobile pedestrian by still relying on consumer-grade GPS receivers. The results are small-sized, however, promising.
