Measurement method for analysing the propagation of eletromagnetic navigation signals

A measuring method for analyzing the propagation of electromagnetic navigation signals, wherein at least one representative transmitting unit, having a chronological signal feed scheme unambiguously assigned to the navigation signal, is assigned to each of the navigation signals.The representative transmitting units are at least intermittently operated offset in time. A characteristic transmission-free leader pause duration and transmission-free trailer pause duration or a characteristic transmitting duration is assigned to each representative transmitting unit.An analysis unit is coupled to a receiving unit and a time-dependent amplitude detection is carried out, wherein the time curve of the received amplitude values is analyzed by the analysis unit to assign the representative transmitting unit to timeslots of the received amplitude values. The pause durations and/or the transmitting durations in the time curve are analyzed and the origin transmitting units of the signal are ascertained on the basis of these items of information.
