Localization systems based on ultrawide bandwidth (UWB) technology have been recently considered for indoor environments, due to the property of UWB signals to resolve multipath and penetrate obstacles. However, line-of-sight (LoS) blockage and excess propagation delay affect ranging measurements thus drastically reducing the localization accuracy. In this paper, we first characterize and deriv...

Location context plays a valuable role in ubiquitous computing, and is still a central area of interest for many researchers. We present an easy-to-deploy location sensing system using acoustic spread-spectrum techniques and hyperbolic multilateration, and a scheme for representing and processing location information using switching algebra.

Abstract. The estimation of the six-degree-of-freedom position and orientation an end effector is high interest in industrial robotics. High precision data rates are important requirements when choosing adequate measurement system. In this work, a pose setup based on laser multilateration described together with principle self-calibration strategies used setup. experimental setup, 200 Hz achiev...

We propose three indoor localization algorithms, namely the leveled nearest-neighbor, leveled multilateration and leveled Bayesian inference, to locate stationary objects (books, merchandise) by affixing passive RFID tags to them. The algorithms use a number of passive tags deployed on the known coordinates as reference points. The simulation results show that the proposed leveled detectable co...
