This study presents a method for improving the accuracy of conventional Pedestrian Dead Reckoning (PDR) using GPS satellite information in indoor environments. The accuracy of PDR is limited by the performance of inertial sensors because the errors caused by users' stride prediction and drift of a gyroscope continuously accumulate, resulting in large errors in predicted trajectories. We employ a neural network based PDR which mainly uses accelerometer and gyroscope embedded in a smartphone to predict the user's trajectories. To fix PDR's error on time, we use some landmarks which can be detected by another neural network that leverages GPS satellite information such as S/N ratio and azimuthal angles to predict if the user is close to windows in a building. Then, we fuse these two predictions based on the particle filter to predict a more accurate user's trajectory. We evaluated our framework using data obtained in different buildings in our campus and confirmed the effectiveness of the framework. |
