Kurzfassung:

Fully autonomous automotive vehicles using localization services are desired by manufacturers and end customers to reduce the number of accidents, the environmental pollution, and the costs of mobility. Much effort has been spent on the development of satellite based localization services with low-cost devices for the mass market. However, all of the developed solutions fail when satellite based localization is not available under indoor conditions like tunnels or dense treetops of avenues. In this case indoor localization systems can be used to fill the gap. The accuracy performance of such systems is hard to compare, due to the heterogeneous information given in the data sheets by the manufacturers. Additionally, the way how the accuracy performance was determined is very often unclear. In view of safety-relevant applications, the quality of such indoor localization systems has to be verified by a reference measurement system using a physically independent measurement principle. As measurement principle for this work electromagnetic sensing has been chosen as this measurement principle is independent of the most principles used by indoor localization systems on the market. The developed measurement set-up is described in this paper. Results of a test run show that the reference measurement system is able to provide a position information with a sufficiently high accuracy for verifications of indoor localization systems.
