A method and device for the remote collection of data from aircraft or ship recorders, using a buoy () which may be ejected in the event of sinking and contains a double memory which stores the positions of the buoy during the drift thereof as well as information relating to the flight or crossing. A two-way radio communication means allows the buoy to transfer the contents of said memories to a remote collection means, which is a reconnaissance aeroplane.

Method and device for the remote collection of data from aircraft or ship recorders

The invention concerns a temporal and spectral submarine locating method, characterised in that it includes equipping the systems or mobile objects to be located and/or identified, with acoustic transmitters transmitting aperiodic signals with a predetermined pseudo-random sequence; deploying, over the working zone where the systems and moving objects to be located are found, one or several measuring points provided, each with an acoustic receiver, with a time scale reference and a measuring point locater; transmitting to a processing centre data derived from the measuring points where, at every time of detection on a given frequency band, precise dating is associated in a time scale referential with a position of the measuring point in a spatial referential; the whole set of data derived from the different measuring points being assembled at the processing centre to be operated on by level 2 correlation with the pseudo-random reference sequences corresponding to each of the searched transmitters.
