Abstract
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 (m.sub.100), 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 (m.sub.100) measures the components of the magnetic field H.sub.x and H.sub.y in the reference point O'xy, a circuit calculates the components of the field H.sub.X an H.sub.Y 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 H.sub.x an H.sub.y and values X.sub.p and Y.sub.p of the position stored in the memory.
