Passive acoustic source positioning for a marine seismic survey

摘要

A method of passive acoustic source positioning of sea-going platforms is disclosed. The method includes positioning of RGPS pods and AHRS acoustic sensors on a fixed surface. Further, the method includes positioning an air gun including gun strings and positioning a set of reflective nodes (sonar bells) along each gun string on each gun cluster position with known fixed offsets. The reflective nodes will reflect the echo from the AHRS acoustic sensor, which will accurately capture their position and transmit the position data to a surface vessel.
