“…This baseline will serve as the reference for comparing and evaluating the performance with channel 5, now. The evaluation is done in a structured indoor environment by using 8 Qualisys Arqus A9 high-performance cameras 1 . Figure 5-(a) illustrates the comparison between the UWB and MoCap traces, while Figure 5-(b) displays the histogram representing the error.…”

“…In recent years, there has been a growing emphasis on integrating positioning systems into Internet of Things (IoT) and Industrial Internet of Things (IIoT) networks, mainly sparked by the technological advancements in compact and energy-efficient devices. Positioning systems can be broadly categorized into active [1], [2] and passive systems [3]. The former systems involve entities equipped with electronic devices that exchange information with the infrastructure to estimate their positions [4], [5].…”

Device-Free localization is a promising technique for indoor positioning in infrastructures, as it eliminates the reliance on custom and costly hardware. In this study, we present the development of a compact and cost-effective bistatic radar sensor that utilizes DW3000 UWB transceivers. The effectiveness of the sensor was evaluated through comprehensive assessments of various channels, with particular emphasis on channel 9, employing Channel Impulse Response analysis. To enhance the accuracy of time delay estimation for multipath components scattered by moving targets, we developed a weighting function. The experimental results demonstrate the potential of device-free localization sensors as a viable solution for indoor positioning systems, offering enhanced accessibility and cost reduction compared to traditional approaches.

“…In the case of RF-based localisation systems the fundamentals ranging techniques to estimate the distance from two nodes are: Received Signal Strength (RSS); Time of Arrival (ToA); Time Difference of Arrival (TDoA) and Angle of Arrival (AoA). RSS is the simplest approach to estimate the distance between two nodes [23], [24]. In this case, the path loss model is exploited to estimate the distance by measuring the signal's received power.…”

Determining assets position with high accuracy and scalability is one of the most investigated technology on the market. The accuracy provided by satellites-based positioning systems (i.e., GLONASS or Galileo) is not always sufficient when a decimeter-level accuracy is required or when there is the need of localising entities that operate inside indoor environments. Scalability is also a recurrent problem when dealing with indoor positioning systems. This paper presents an innovative UWB Indoor GPS-Like local positioning system able to tracks any number of assets without decreasing measurements update rate. To increase the system's accuracy the mathematical model and the sources of uncertainties are investigated. Results highlight how the proposed implementation provides positioning information with an absolute maximum error below 20 cm. Scalability is also resolved thanks to DTDoA transmission mechanisms not requiring an active role from the asset to be tracked.
