METHOD FOR AIDING THE LOCALIZATION OF SUBMERGED OBJECTS EMITTING AN ACOUSTIC SIGNAL

摘要

The present invention relates to a method of assisting the location of at least one immersed object emitting an acoustic signal, such as a black box, said method comprising the following steps: a) launching (10) of at least one subsurface equipment provided with an acoustic detection module, said subsurface equipment being able to move freely under water and on water, b) immersion (11) of said subsurface equipment to a depth predetermined; c) following detection, by said acoustic detection module, of the acoustic signal emitted by the immersed object, raised to the surface (13) of said subsurface equipment and d) transmission (14) by said subsurface equipment of a first signal to a remote processing station, said first signal comprising the position of the subsurface equipment after going back to the surface and information representative of the detection of said acoustic signal and / or representative of said acoustic signal.
