    摘要: In marine seismic exploration, it is common for a vessel to tow a streamer, which includes a plurality of pressure sensitive detectors or hydrophones, for the purpose of acquiring seismic signals representative of the underlying structure of the earth. To aid in the interpretation of these seismic signals, it is necessary to know the precise location of the streamer at the time the signals are acquired. Disclosed herein is a method and system for providing a model representative of the location of the streamer relative to the location of the vessel. In one aspect, the system includes an apparatus mounted at the stern of the vessel and coupled to the near end of the streamer. This apparatus is adapted to provide measurements of the yaw and pitch of that portion of the streamer adjacent the vessel. These measurements are employed in the generation of the position model.
