METHOD AND APPARATUS FOR POSITIONING OF SEISMIC SENSING CABLES.

摘要

The present invention provides a method and apparatus for determining the position of a seismic cable being used to perform a marine seismic survey. The apparatus includes at least one seismic sensor (115) and a plurality of sources (125) deployed in a manner that is structurally independent of the seismic sensors (115) and adapted to provide a positioning signal (130) distinguishable from a seismic survey signal (118) to the seismic sensors.
