Multisensor Data Fusion for High Accuracy Positioning on Mobile Phones

Analysis of human geographical orientation is a crucial issue to understand the user's actual demand on context based information. As the limitations in accuracy of satellite based positioning especially in urban environments and network based positioning are well known, a novel framework concept based on data fusion of multiple sensors build-in handsets will enable to characterize the user's situation and allow automated analysis with semantic mapping functionality. In this paper, the first approach for high accuracy multi sensor orientation tracking by the use of a mobile phone is discussed.
