This paper describes the analysis and the improvement of an electromagnetic tracking system (EMTS) for surgical survey. The system is based on inductive coupling between five transmitting coils and a small coil censor, in order to overcome line-of-sight dependence.The performance of the control loop of coils excitation currents is investigated, ruling out coupling side effects which may potentially affect system's performance.The results show a significant reduction of both voltage and current error, which may result in a more accurate position estimation.
