A simple method for passivation of a component is presented which is particularly suitable for processing high-viscosity plastics. Here a number of article numbers are stored in a memory which are assigned, on the one hand, to a number of articles and on the other hand to a number of different article number types. At a receiving end, the respectively received data can be provided for a positioning of a device comprising a satellite signal receiver. The center rod has two flanges, an annular groove between the flanges and a bottom hole for a spring to fit in. The transmit power setting and the variable spreading factor is adjusted based on the received power.
