摘要
The determination of the location of a submerged marine streamer 20 towed behind a seismic exploration vessel is effected by means of an array of at least three transponders 10, 12, 14 secured to the ocean floor which generate distinguishable acoustic pulses upon a command signal from the ship. These signals are received by acoustic receivers 34 housed in the streamer and by the ship. The distance to each acoustic receiver may be triangulated from the data generated. IMAGE
