Abstract:
In order to evaluate indoor positioning technologies according to industrial standards, this paper presents a new mathematical approach based upon EN ISO 9283 giving a precise definition of positioning accuracy and precision. Following this approach, two indoor positioning systems (IPS) applying ultra wide band (UWB) and ultrasound technology have been tested in the the SmartFactoryKL to get a better understanding of their suitability for industrial location-based services (LBS). Testing has been conducted under optimal operating conditions and under realistic shop-floor conditions as well. Since both technologies show highly variable performance, measurement results are discussed and recommendations for further evaluation and research in the field of location technologies are given.
