ABSTRACT:
The disclosure pertains to the localization of a station by another station in a network for the transmission of data in packets, each packet being formed by a header followed by an information field at a carrier frequency that varies according to a linear ramp. The method consists, in a first station, in sending out an interrogation packet with a designation of a second station, in the second station, upon the reception of this interrogation packet, in sending a signal in continuity with the field of the packet received and according to the same ramp and, in the first station, in measuring the delay of this signal, when it is received, with respect to a signal produced in the first station after the field of the packet sent out and in deducing the distance between the two stations from the delay. Application to the measurement of distances.
