Zusammenfassung:A device for determining the position in the water of an elongate element (a seismic streamer for example) towed while submerged, by means of measuring elements such as compasses and pressure gauges spaced apart along said elongate element. Said compasses and pressure gauges are disposed inside profiled bodies firmly secured to sleeves fixed about said elongate element and transmit the measurements, by means of a hertzian wave transmission assembly, to a sensor inside the elongate element, which is connected by a transmission cable to a reception assembly connected to a central unit installed in the towing ship.
