A method of assisting the deployment/retrieval of linear acoustic antennas towed by a vessel, said linear antennas each having geophysical data sensors, means for measuring the distance of at least one adjacent linear antenna, during the course of which at least one of said linear acoustic antennas has at least longitudinal mobility in relation to said vessel, including: at least one phase for configuring cells (Cn) each defined by a central position corresponding to a distance-measuring means (T), and by at least one peripheral position corresponding to another distance-measuring means (T) in proximity to said distance-measuring means (T) for said central position, reference distances between said central positions and said peripheral positions being predetermined; and at least one phase for controlling said central and peripheral positions with respect to said reference distances, by establishing communication between at least some of said distance-measuring means (T).
