The present invention relates to an initialisation beacon for a vehicle at rest, in particular for a system giving assistance in driving, in operation and in maintenance, constituted by a superposition of structures with cross-members Si, each structure with cross-members being constituted by a first electrical cable Ci1 and a second electrical cable Ci2, these being parallel to each other over a major part of their length, the first electrical cable Ci1 crossing over the second electrical cable Ci2 so as to form a succession of magnetic nodes N; characterised in that: - the magnetic nodes Nij of a given structure with cross-members Si are distributed, with a spatial period, along the said structure with cross-members; and - the said structures with cross-members Si are supplied successively per pair Pmn and successively at a clock frequency FH and at a data frequency FD. <IMAGE> |
