Ultra-Wideband Positioning using Reflections from Known Indoor Features

Ultra-wideband Methods for Ugv Positioning: Experimental and Simulation Results

U.S. Army RDECOM-TARDEC, in collaboration with Oakland University and JADI Inc., is currently conducting novel research devoted to obtain fine-grain (centimeter accuracy) indoor positioning for unmanned ground vehicle (UGV) navigation applications using Ultra-Wideband (UWB) technologies. This paper will present recent results from advanced closed-form solutions and analyses for positioning erro...

Indoor Positioning with Uwb Technology

Ultra Wideband Indoor Positioning Technologies: Analysis and Recent Advances †

In recent years, indoor positioning has emerged as a critical function in many end-user applications; including military, civilian, disaster relief and peacekeeping missions. In comparison with outdoor environments, sensing location information in indoor environments requires a higher precision and is a more challenging task in part because various objects reflect and disperse signals. Ultra Wi...

Horizontal dilution of precision-based ultra-wideband positioning technique for indoor environments

Ultra-wideband (UWB) technology provides considerable performance in many indoor localization problems thanks to its very wide spectrum and high-resolution characteristics. In this paper, we propose using the horizontal dilution of precision (HDOP) to decrease the localization error in indoor environments for UWB localization systems. To achieve this aim, first we determine the positioning accu...

A Novel Approach based on UWB Beamforming for Indoor Positioning in None-Line-of-Sight Environments

Accurate wireless indoor positioning in non line-of-sight (NLoS) environments is an open research topic due to interfering dense multipath propagation. The key challenge is to reliably detect the direct path (DP) from the transmitter to the receiver so as to enable accurate positioning calculations. In our contribution a novel approach called ”BeamLoc” has been introduced to perform this task. ...
