Using Ultra-Wideband Technology in Vehicles for Infrastructure-free Localization

Abstract: In this paper, we investigate using Ultra-Wideband (UWB) technology in vehicles for localization as well as other possible infrastructure-free applications. To that end, we first introduce the on-vehicle UWB anchor layout, then conduct a theoretical analysis to shed light on the capabilities and limitations of using UWB anchors with this layout. To verify the analysis conducted, extensive field trials are performed, which yield results that match the predictions of the conducted analysis. Finally, Virtual Pedestrian Traffic Light (VPTL), an infrastructure-free pedestrian traffic light system is introduced as an example application of the presented approach.
