An Ultra-Wideband System for Vehicle Positioning

Systems supporting traffic safety require precise information on a vehicle position. The paper contains a proposal for a vehicle localization system based on ultra-wideband (UWB) technology. The system allows for vehicle positioning with sub meter accuracy. The paper presents a system concept and an algorithm used for position calculation. The algorithm consists in selection of a system configuration in order to decrease the positioning uncertainty. The system concept was verified with a developed system demonstrator. The paper contains a description of the devices comprising the system. Exemplary results of outdoor demonstrator tests are included and discussed. The tests confirmed efficiency and attractiveness of the proposed solution.
