In the past decades, short multipath effect is one of the most important error sources in global navigation satellite systems (GNSS) navigation, and seriously affects the positioning precision. Therefore, some algorithms based on traditional Kalman filtering (KF) have been proposed to overcome the short multipath effect, for example extended KF (EKF), adaptive KF (AKF) and constrained KF (CKF). However,...
The need for indoor pedestrian navigators is quickly increasing in various applications over the last few years. However, indoor navigation still faces many challenges and practical issues, such as the need for special hardware designs and complicated infrastructure requirements. This paper originally proposes a pedestrian navigator based on tightly coupled (TC) integration of low-cost microelectromechanical...
The locations of WiFi access points (APs) are important for WiFi positioning, especially when a propagation model is used. However, AP localization is usually challenging in a new environment because it is hard to obtain parameters for the propagation model, such as the path-loss exponent without the presence of surveyed database. This paper introduces a novel crowdsourcing method for automatic AP...
