This paper describes the characterisation of an optical tracking system that allows to accurately locate the position of a magnetic sensor used for measuring the magnetic field generated from inductive charging of electrical vehicles. This paper forms part of the metrology for inductive charging of electric vehicles (MICEV) project. 2D measurements have been successfully carried out with the optical tracking system and the data acquisition has been automated by means of a dedicated software routine. The experimental setup, results, data and uncertainty analysis are presented in this paper. We show that the expanded uncertainty of the tracking system is ±0.64 mm with a coverage factor $k$ = 2, providing a coverage probability of approximately 95%.
