A seismic survey system having a source array (11) coupled to a deflector device (15) that controls the position of the source array. A positioning system unit (16) is mounted on the source array to provide a signal to a controller, informing the controller of the current position of the source array so that the controller can control the position of the deflector device (15) and the coupled source array. A seismic source (14) on the source array may be triggered when the source array is at a desired location as measured by the positioning system unit. The deflector device (15) comprises one or more wings (18) in a generally vertical or, alternatively, in a generally horizontal arrangement disposed adjacent to a central body (19). The streamlined central body has connection points that allow the deflector device (15) to be connected to a tow cable (13) from the tow vessel (12) and to the source array (11).

1. A method of positioning a source array in tow behind a vessel, comprising: determining the position of the source array; andindependently steering a deflector device coupled to the source array to move the source array to a desired position, wherein the deflector device has a body and one or more wings that are positioned at a lateral distance from the body in a crossline direction. 2. The method of claim 1, further comprising: controlling the deflector device to steer the source array to the desired position. 3. The method of claim 2, further comprising: determining the position of the source array, andproviding the position to the controller. 4. The method of claim 3, further comprising: triggering a seismic source on the source array when the source array is at a desired position. 5. The method of claim 2, wherein the deflector device further comprises: an actuator disposed within the body. 6. The method of claim 5, further comprising: transmitting a control signal to the actuator; andmoving the one or more wings with the actuator, wherein the movement of the one or more wings steers the source array. 7. The method of claim 1, further comprising: coupling a second independently steerable deflector device to a second source array for controlling a second position of the second source array. 8. The method of claim 1, further comprising: detecting acoustic signals indicating obstructions in the path of the source array; andadjusting the deflector device to steer clear of the detected obstructions. 9. The method of claim 8, further comprising: operating an acoustical transducer and receiver in a range typical for sonar devices. 10. The method of claim 9, further comprising: sweeping the acoustic transducer and receiver in many directions. 11. A seismic survey system for use in water, comprising: a source array towed by a first tow cable;a deflector deflecting a second tow cable, wherein the deflector comprises a body and one or more wings;a distance rope coupling the first tow cable to the second tow cable; anda winch attached to the distance rope, wherein the winch adjusts a length of the distance rope to modify a position of the source array. 12. The seismic survey system of claim 11, further comprising: a controller for controlling the position of the source array. 13. The seismic survey system of claim 12, further comprising: a positioning system unit attached to the source array, wherein the positioning system unit provides a signal to inform the controller of the position of the source array. 14. The seismic survey system of claim 13, wherein a seismic source on the source array is triggered when the source array is at a desired location. 15. The seismic survey system of claim 12, wherein the controller is positioned at a location selected from a towing vessel, the winch, and combinations thereof. 16. The seismic survey system of claim 11, wherein the winch comprises: a reel for winding the distance rope onto the winch;an actuator for rotating the reel; anda housing adjacent to the reel. 17. The seismic survey system of claim 11, further comprising: an acoustical transducer and receiver coupled to the source array; anda controller, wherein the controller adjusts the winch to steer clear of an obstruction located by the acoustical transducer and receiver. 18. A seismic survey system for use in water, comprising: a source array;a steerable deflector device coupled to the source array, wherein the deflector device comprises a body and a wing that is positioned at a lateral distance from the body in a crossline direction, wherein the wing controls the position of the source array and is adjustably attached to the body; anda positioning system to determine a location of the source array. 19. The seismic survey system of claim 18, wherein the positioning system comprises a positioning unit mounted on the source array, and the positioning unit provides a controller with the location of the source array. 20. The seismic survey system of claim 19, wherein the positioning system is selected from a global positioning system, a satellite positioning system, an acoustic network, and a laser system.
