ABSTRACT:
Method and means are provided for determining the position of a submerged marine streamer towed behind an exploration vessel. A sonic ring around feedback system is employed to redundantly ascertain the distance to various hydrophones housed in the streamer from an outboard mounted transponder capable of generating high frequency sound pulses of short duration.
