SUBMERGED MARINE STREAMER LOCATOR

摘要

Method and means are provided for determining the position of a submerged marine streamer towed behind an exploration vessel. An array of at least three transponders secured to the ocean floor generate distinguishable acoustic pulses upon a command signal from the ship. These signals are received by hydrophones housed in the streamer and by the ship. The distance to each hydrophone may be triangulated from the data generated.
