Local Positioning Systems (LPS) are supposing an attractive research topic over the last few years. LPS ad-hoc deployments of wireless sensor networks for particularly adapt to environment characteristics in harsh environments. Among LPS, those based on temporal measurements stand out their trade-off among accuracy, robustness and costs. But, regardless architecture considered, optimization dis...

The continuous rise of mobile technology in everyday life has led to an increasing demand for location-based services for handheld applications and autonomous systems. In recent time, a shift of interest towards indoor localization can be observed where global navigation satellite systems, such as the Global Positioning System, are mostly not available. The hardware for positioning and navigati...

In this manuscript, we formulate the problem of source localization based on Time Differences of Arrival (TDOAs) in the TDOA space, i.e., the Euclidean space spanned by TDOAmeasurements. More specifically, we show that source localization can be interpreted as a denoising problem of TDOA measurements. As this denoising problem is difficult to solve in general, our analysis shows that it is poss...

The technology of wireless sensor networks (WSNs) is developing rapidly, and it has been applied in diverse fields, such as medicine, environmental control, climate prediction, monitoring, etc. Location one the critical fields WSNs. Time difference arrival (TDOA) widely used to locate targets because a simple model, easy implement. Aiming at problems large deviation low accuracy nonlinear equat...

Low-power devices such as cell phones, and wireless routers are commonly used to control Improvised Explosive Devices (IEDs) and as the communication nodes for the sake of command and control. Quickly locating the source of these signals is ambitious, specifically in a metropolitan environment where buildings and towers may cause intervention. This presents a geolocation system that compounds t...

In this study, we consider the use of seismic sensors for footstep localization in indoor environments. A popular strategy of localization is to use the measured differences in arrival times of source signals at multiple pairs of receivers. In the literature, most algorithms that are based on time differences of arrival (TDOA) assume that the propagation velocity is a constant as a function of ...

This paper describes an application of a dual satellite geolocation (DSG) system on identifying and locating the unknown source of uplink sweeping interference. The geolocation system integrates the method of joint time difference of arrival (TDOA) and frequency difference of arrival (FDOA) with ephemeris correction technique which successfully demonstrated high accuracy in interference source ...
