“…These results confirm those of Jimenez et al [38,39] and results of Dotlic et al [44] in static when using mean calculation. UWB is accurate up to 10 cm in static and behaves like a sphere around the target with a range value of 10 cm shown in Figure 2.…”

Many applications in the context of Industry 4.0 require precise localization. However, indoor localization remains an open problem, especially in complex environments such as industrial environments.In recent years, we have seen the emergence of Ultra WideBand (UWB) localization systems. The aim of this article is to evaluate the performance of a UWB system to estimate the position of a person moving in an indoor environment. To do so, we implemented an experimental protocol to evaluate the accuracy of the UWB system both statically and dynamically. The UWB system is compared to a ground truth obtained by a motion capture system with a millimetric accuracy.

“…Throughout this paper, several TREK1000 development kits manufactured by Decawave were used. According to [26] and [11], TREK1000 development kits are the best UWB commercial products for ranging. The nodes are fully compliant with the IEEE 802.15.4-2011 UWB standard and make it possible to achieve ranging measurements using two-way ranging measurements at a rate of 3.57 Hz.…”

In recent years, several Ultrawideband (UWB) localization systems have already been proposed and evaluated for accurate position estimation of pedestrians. However, most of them are evaluated for a particular wearable sensor position; hence the accuracy obtained is subject to a given wearable sensor position. In this paper, we study the effects of body wearable sensor positions i.e., chest, arm, ankle, wrist, thigh, fore-head, hand, on the localization accuracy. The conclusion drawn is that the fore-head is the best, and the chest is the worst body sensor location for tracking a pedestrian. While the fore-head position is able to set an error lower than 0.35 m (90th percentile), the chest is able to set 4 m. The reason for such a contrast in the performance lies in the fact that in NLOS situations, the chest as an obstacle is larger in size and thickness than any other part of the human body, which the UWB signal needs to overcome to reach the target wearable sensor. And so, the large errors arise due to the signal arriving at the target wearable sensor from reflections of a nearby object or a wall in the environment.

The Ultra-wideband location technology provides high accuracy of indoor positioning. However there is still little work on the accuracy of this solution, especially when monitoring moving objects. The paper shows the results of the measurement of the UWB indoor positioning system accuracy in stationary conditions and shows how the accuracy changes when the monitored object is on the move. It is also measured how the orientation of the antenna influences the accuracy. We show, that while the UWB provides very small error in the stationary scenario (within few centimeters), the accuracy significantly decreases when the device is moving and the average error grows to up to 20 cm. The experimental probability distribution function for different measurement scenarios is presented, showing how the location estimation variates in time and how this is correlated with the actual position of the device.
