Abstract: The invention relates to a receiver of very high frequency band signals transmitted by a transmitter, comprising an antenna, a band-pass filter, a software-defined radio adapted to receive the signals filtered by said band-pass filter via a first input and to digitise said signals with a predetermined sampling rate in a predetermined sampling frequency band so as to obtain a digitised signal, characterised in that the receiver comprises at least two extraction modules each capable of receiving the digitised signal and of extracting part of the digitised signal, referred to as extracted signal, in a natural frequency channel, and at least two demodulators each capable of receiving an extracted signal and of demodulating said signal so as to retrieve data. The invention further relates to a very high frequency signals transmitter and to a corresponding transmission method.

Abstract: A method for geo-locating the raw data exchanged between an aircraft and a VHF receiver is provided. Each item of raw data includes an identifier of the aircraft transmitting this item of data. The method includes obtaining position data of the aircraft. In this regard, the position data includes a piece of information which represents the identifier of the aircraft. The method also includes correlating the raw data and the position data by determining the data that has an identical identifier.
