Indoor Positioning Techniques Based on Wireless LAN
This paper describes the techniques used and details the experimental results of the research, as well as describing the methods used and describing the techniques successful in relation to signal strength based positioning. Expand
How feasible is the use of magnetic field alone for indoor positioning?
Tests were carried out to investigate the feasibility of using magnetic field alone for indoor positioning, and to take advantage of local anomalies to create a location fingerprinting methodology. Expand
Differences in RSSI readings made by different Wi-Fi chipsets: A limitation of WLAN localization
Wi-Fi positioning has found favour in environments which are traditionally challenging for GPS. The currently used method of Wi-Fi fingerprinting assumes that the devices used for training andExpand
Positioning Systems in Intelligent Transportation Systems
From the Publisher: Positioning systems, which determine the location of cars, trucks, buses, trains, and airplanes, are critical in the use of intelligent transport systems (ITS) to improve theExpand
Method for yielding a database of location fingerprints in WLAN
Location fingerprinting in wireless LAN positioning has received much attention recently. One of the key issues of this technique is generating the database of fingerprints. The conventional methodExpand
A critical evaluation of location based services and their potential
This Editorial lead article for the Journal of Location Based Services surveys this complex and multi-disciplinary field and identifies the key research issues and synthesises the key issues for this new field. Expand
Improving Adaptive Kalman Estimation in GPS/INS Integration
The central task of GPS/INS integration is to effectively blend GPS and INS data together to generate an optimal solution. The present data fusion algorithms, which are mostly based on KalmanExpand
Comparison of Interpolation Algorithms in Network‐Based GPS Techniques
This paper compares the interpolation methods used in network-based GPS techniques, including the linear combination model, distance-based linear interpolation method, linear interpolation method,Expand
