Abstract: A method and apparatus for determining the position of a plurality of seismic echo receivers on a towed cable by interpolating values obtained by measuring, by means of at least one device positioned among said receivers, the angle between the tangent to the cable and a fixed and known direction. The measuring device can also include apparatus for measuring its depth and its distance from a generator of seismic waves. This provides for more effective use of processes which involve the addition of seismic traces in marine seismic prospecting.
