Accurately determining one's position has been a recurrent problem in history [1]. It even
precedes the first deep-sea navigation attempts of ancient civilizations and reaches the …

It has been considered a fact that GPS performs too poorly inside buildings to provide
usable indoor positioning. We analyze results of a measurement campaign to improve on …

Purpose To assess validity of the Personal Activity Location Measurement System (PALMS)
for deriving time spent walking/running, bicycling, and in vehicle, using SenseCam as the …

Indoor localization technologies hold promise for many ambient intelligence applications,
including in-situ navigational assistance for individuals with wayfinding difficulties. Given …

In this paper we propose a reliable acoustic indoor positioning system fully compatible with
a conventional smartphone. The proposed system takes advantage of the smartphone audio …

In the underwater acoustic (UWA) channel, the line-of-sight (LOS) path has the
characteristics of stable magnitude and continuous phase, which is seldom affected by the …

Dr. Gérard Lachapelle is a Professor of Geomatics Engineering at the University of Calgary
where he is responsible for teaching and research related to location, positioning, and …

The primary focus in this paper is on position estimation of an unknown sensor node in
indoor environment. Received signal strength (RSS)-based algorithm was used for position …

Global Positioning System (GPS) currently fulfills the positioning requirements of many
applications under Line-Of-Sight (LOS) environments. However, many Location-Based …

This paper focuses on the positioning algorithm suitable for harsh indoor environment such
