The popularity of positioning satellite systems in open areas has led to a high demand for systems suitable for harsh environments, where the former fail. Wireless localization and inertial navigation have emerged as the most valuable alternatives to offer positioning in such environments. However, the characteristics of the wireless propagation channel in harsh environments are dynamic and unpredictable...
The hybrid localization techniques have attracted significant research interest since a variety of localization metrics can be easily obtained by most wireless devices. This paper presents a hybrid localization scheme that combines received signal strength (RSS) and round-trip time (RTT) information. It is based on a RSS ranging technique that dynamically update the model that best fit the RSS information...
The final precision achieved by a wireless location system depends basically on the accuracy of the range estimates and on the geometric distribution between anchors and target, being the second issue easier to manage in the design of a wireless location system. The results related to the impact of the geometric distribution, addressed for GNSS location systems, cannot be used directly to other wireless...
