Abstract: This talk will discuss two approaches of indoor navigation: using Wi-Fi and Ultra-wideband (UWB). The implementation of Wi-Fi based approach is illustrated with a project done at the main building of Technical University of Berlin. The design and integration of indoor topographic and sensor space models using 3D GIS and the development of corresponding database schema for localization are discussed. The second approach describes a UWB based indoor localization platform developed at Fraunhofer IIS, Germany. The use of Time Difference of Arrival (TDoA) technique for localization is discussed with a comparison of different Bayesian positioning algorithms.
