Abstract: The object of the invention is a method and an arrangement for determining the location and/or speed of an object configured to move along a controlled trajectory, in connection with which object is fitted a measuring device (1 ) measuring at least the magnetic field acting on the object in its different locations, which measuring device comprises means (4) for measuring the magnetic field, from the measuring data received from which means a magnetic footprint describing the magnetic field acting on the object in its different locations is formed, which magnetic footprint is recorded in connection with a teaching run, or with self-learning, for later use. The location of the object after a teaching run is determined by measuring in essentially realtime in the direction of the three coordinates X, Y, Z of the magnetic field acting on the object moving along a controlled trajectory and by comparing the measurement results to a magnetic footprint recorded in advance and also by deducing as a result of the comparison the exact location of the object on its path of travel.
