摘要

Method for determining an orientation of a data acquisition system put into operation on a seabed, and data acquisition system.This is a method for determining the orientation of a data acquisition system put into operation in a seabed, where the method includes measuring horizontal magnetic fields using detectors on the data acquisition system, while the system of aquisiu00e7 The data will wheel and descends to the bottom of the sea or rises from the bottom of the sea.Magnetic fields are measured after the horizontal resting data acquisition system is found on the seabed. A direction of orientation of the data acquisition system on the seabed can be determined based on maximum and minimum horizontal magnetic fields measured during the descent, and on the basis of the horizontal magnetic fields at rest.
