High-Precision Ad-Hoc Indoor Positioning in Challenging Industrial Environments

This paper addresses the problem of providing high-precision positioning in industrial environments. Such environments are extremely challenging due to the adverse effects of multipath fading caused by the abundance of metallic objects, the physical layout of the environment which is often complex, and the lack of fixed positioning system infrastructure. Several technologies are assessed with regard to these challenges and their shortcomings are outlined. A solution based on an ad-hoc system is outlined in which we propose the use of an ad-hoc multimodal positioning system to achieve our goals.
