ABSTRACT A method for determining the position of a marine seismic receiver cable of the type which is towed behind a seismic survey vessel through the sea, wherein the azimuth and the distance from the vessel to points along the seismic receiver cable are measured, and the coordinates of these points are calculated on the basis of these values. A hydroacoustic measurement method is utilized, based on a super-short baseline system integrated with a gyrocompass, for measuring the azimuth and distances in accordance with signals from trans- ponders, beasons, responders and/or similar instruments installed on or within the seismic receiver cable.
