Abstract
This paper presents a method for the simultaneous and precise localization of multiple coils in a shelf based on low frequency magnetic fields. The separation of the signals is achieved by modulating the coils' resonance frequencies using orthogonal codes. Accuracy measurements were conducted with a setup consisting of one exciter loop, four localization coils and eight receiver loops. Results show the robustness of the proposed localization method for a wide range of positions. Furthermore, we investigated the influence of conductive objects positioned in the localization area on the localization accuracy.
