This paper presents a new conception of a positioning technology concept for aircraft structural assembly, for instance the manufacturing of the fuselage sections from shell panels and floor grids, the alignment of the sections to build the fuselage, and the joining of wings and tail units to the fuselage. The positioning system features a modular, reconfigurable, and versatile solution for various aircraft dimensions and different applications. It provides the customer with a holistic solution that considers the positioning task taking into account the operation conditions and the environmental influences within the very same control unit. The positioning system consists of three main modules that communicate over a standardized interface: A large-scale metrology system for an accurate identification of the positions and orientation of the aircraft components, a mechanical system for the handling of these components and a control system.
