ABSTRACT:
A method is disclosed of tracing a path to be taken by a mobile terminal receiving electromagnetic waves transmitted by transmitter stations, the path being traced by an operating platform, which method comprises a learning phase comprising a taking of the path during which, exclusively on the path, a periodic routine learning recording of successive groups of samples is made in a route memory, a sample comprising at least one value of each of the frequencies received at each of the periodic recordings, and a receive level associated with that frequency, and a comparison of the received levels between a group of pnsamples recorded during a sampling of rank n and one recorded preceding group of rank lower than n, a comparison criterion discriminating between remarkable groups and ordinary groups. The method further comprises an operating phase during which the mobile terminal takes the path, and comprising periodic recording of groups of Pisamples each comprising a value of each of the frequencies received at each recording and a receive level associated with the frequency, comparing each group of samples with one of the remarkable groups of samples, the comparison producing a comparison result, a presence or absence indication on the path to be taken by comparing the comparison result and a comparison criterion, and processing one or more of the presence indications to decide if the mobile terminal is on the path or not.
