Summary:Apparatus for the dynamic positioning of a moving body such as a boat alongside a drilling platform at sea by means of a magnetic field in a plane OXY in which the moving body comprises one or more magnetometers (m100), and an apparatus for taking bearings on the angle theta , which a moving reference point O'xy makes with the reference point OXY. The magnetometer (m100) measures the components of the magnetic field Hx and Hy in the reference point O'xy, a circuit calculates the components of the field HX an HY in the fixed reference point and other circuits determine the position of the moving body. A circuit prepares control signals for the motor of the moving body from the values of Hx an Hy and values Xp and Yp of the position stored in the memory.
