Device for determining the relative position of elongate members towed behind a ship |
摘要 |
Device for determining the relative position of at least one seismic streamer comprising acoustic pulse sensors, with respect to a seismic streamer comprising acoustic pulse transmitters, all of said streamers being towed behind a ship, comprising a telemetrical system for measuring the distance between pulse sensors and pulse transmitters by the determination of the travel time of pulses between different pulse transmitters and corresponding pulse sensors and a viewing system for displaying the so-measured distance.
