  • Marine seismic surveying
    Patent number: 10338258
    Abstract: A system for acquiring a marine seismic survey makes use of a propelled vessel (40) towing at least a seismic source assembly (100) behind it. The navigation control system (42) of the propelled vessel is instructed to steer the propelled vessel in response to position information repetitively generated by a source global positioning system (GPS, 130) which forms part of the seismic source assembly being towed. The position information from the source GPS is thus used to navigate the seismic source assembly to a target location. The position information from the source GPS is also used to trigger activation of the seismic source when the seismic source is located within a pre-determined distance from the target location.
