Acoustic modem-based guiding method for autonomous underwater vehicle for marine seismic surveys

摘要

An autonomous underwater vehicle (AUV) records seismic signals during a marine seismic survey. The AUV includes a communication device configured to acoustically receive location information from plural transducers of a vessel, wherein each transducer of the vessel transmits its own geographical location; a navigation system configured to receive the location information from the communication device and to calculate current and target positions of the AUV; a propulsion system configured to drive the AUV from the current position to the target position; and a seismic sensor for recording seismic data after reaching a final target position.

1. An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising:
a communication device configured to acoustically receive location information from plural transducers of a vessel, wherein each transducer of the vessel transmits its own geographical location; a navigation system configured to receive the location information from the communication device and to calculate current and target positions of the AUV based on the location information; a propulsion system configured to drive the AUV from the current position to the target position; and a seismic sensor for recording seismic data after reaching a final target position.
