Claim 10:
11. The system (9) according to claim 10, wherein the electromagnetic source unit (13) and the electromagnetic receiver unit (14) each comprise at least three coils arranged on axes that are orthogonal to one another; the three coils of the source unit (13) being configured to each emit a variable magnetic field, which excites said at least three coils of the electromagnetic receiver unit (14), thus allowing, through a change generated by at least three coils of the electromagnetic receiver unit (14) due to the excitation, the current position and current orientation of the helmet (10) to be determined based on the change in the magnetic field emitted by the three coils of the electromagnetic source unit (13).
