A method of location of a device comprises providing a map containing several distinct zones, each distinct zone being associated with a displacement law from among a set of several different displacement laws. The displacement law associated with a zone making it possible to estimate more precisely, on the basis of the same measurements received, the direction and the amplitude of the displacement of the device when the latter is situated inside the zone than if any one of the other displacement laws of the set were used. The method also includes an operation of identifying the zone inside which a particle is situated, and then, an operation of using, for the updating of the coordinates of the particle, of just the displacement law associated with the zone identified during the identification operation. |
