A satellite vehicle is an autonomous vehicle with a very low overall height, which can move both in the storage system and in the pre-storage area and is attached to the rack feeder in satellite storage systems instead of a telescopic fork. During storage and retrieval processes, the satellite vehicle detaches from the rack feeder after reaching the x/z coordinate of the storage location and drives into the storage channel. There it can load and unload the loading units independently using a lifting device.
