The performance of a magnetic tracking system is substantially influenced by the positions of its sensors. To optimise these sensor positions, exploited is a performance metric based on the Fisher information matrix and a convex relaxation of sensor selection problem. Optimised sensor positions are presented for a magnetic tracking system with a planar sensor array and a measurement domain consisting of one point.
