In this paper, an indoor positioning system that combines UWB positioning and PDR is introduced. The proposed scheme improves the performance of PDR using UWB ranging data. Length estimation and step detection in traditional PDR are substituted with speed estimation, which is based on deep learning. Heading calculation in traditional PDR is calibrated by UWB ranging data. Finally, improved PDR is combined with UWB ranging. Noble UKF-based algorithm which considers NLOS environment is used for combination. We prove that the performance of UWB ranging-PDR combined algorithm is better than simple UWB positioning or improved PDR algorithm through experiments.
