An Improved PDR/UWB Integrated System for Indoor Navigation Applications

The challenges of the inertial navigation system based pedestrian dead reckoning (PDR) are mainly stochastic errors and serious accumulated errors caused by sensor variance, while the ultra-wideband (UWB) based positioning approaches are vulnerable to the external environment and produce many outliers under non-line-of-sight (NLOS) conditions. To overcome these shortcomings, this paper proposes a ...
