“…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.

“…As the requirements of logistics and manufacturing processes increase, access to precise positional information is becoming a necessity. Depending on the operating conditions for the localization application, different measurement principles [3], [4], [5] and techniques [6], [7], [8] are available. Two of the most common measurement techniques are based on the time-of-arrival (TOA) [6] and the time-difference-of-arrival (TDOA) [7].…”

Precise indoor localization is a major challenge in the field of localization. In this work we investigate multiple error corrections for the ultra-wideband (UWB) technology, in particular the DecaWave DW1000 transceiver. Both the time-of-arrival (TOA) and the time-difference-of-arrival (TDOA) methods are considered. Various clock-drift correction methods for TOA from the literature are reviewed and compared experimentally. The best performing method is extended to TDOA, corrections for the signal power dependence and the hardware delay are added, and two additional enhancements suggested. These are compared to each other and to TOA in positioning experiments. Index Terms-time-of-arrival (TOA), time-difference-of-arrival (TDOA), two-way-ranging (TWR), DecaWave, ultra-wideband (UWB)
