Abstract

Magnetic position and orientation systems offer the advantages of contactless sensing, high precision, robustness and low cost. They are heavily employed in automotive and industrial applications. The standard development process of such system starts with a simulation that is followed by validation with experimental data. This work presents a platform to which different sensors and magnets can be attached, with complete six degrees of freedom for relative movement. It is thus quite flexible in terms of experiments it can perform. A system calibration scheme based on dipole approximation is presented, yielding sensor tolerances and allowing to compute the field of a corresponding magnet.
