To monitor the advance of an orientable drilling head (3), two different magnetic fields are generated in the ground, around a trajectory (10) by means of two conductors (8, 9). The current induced by each magnetic field is allowed to flow through a coil associated with the drilling head. The phase difference between two currents induced in the coil by two different magnetic fields is determined. ...
