Ket : In the automation age, the demands for technologies that facilitate the spatial localization of objects and people have gained a significant degree of attention in industry, research and private life, in recent years [1–4]. Well-established technologies, such as the Global Positioning System (GPS) [5] are almost ubiquitous today and are indispensable in the modern society. They allow the localization and tracking of people and objects on a global scale and have found their way into various supply chain management applications [6]. With upcoming technologies like the Internet of Things (IoT) [7] and Industry 4.0 [8], the need for indoor localization systems with an accuracy in the decimetre-range seems a natural next step in this arena [9–11]. The popularity of localization systems like GPS is based on the fact that they are wireless and provide sufficient accuracy for the target applications. However, for indoor applications, the microwave frequency (satellite signals) used in GPS systems is blocked by walls and other objects which makes localization almost impossible [12]. Additionally, the achieved localization errors lie in a metre-range which is far too high for indoor applications
