System for scanning or inspecting an aircraft or spacecraft surface

A system for scanning or inspecting an aircraft or spacecraft surface structure, comprising:

• at least one ground vehicle carrying at least one first inspection device,
• at least one hovering platform carrying at least one second inspection device,
• wherein the at least one first inspection device is arranged on a first arm arranged on the at least one ground vehicle,
• wherein the at least one ground vehicle comprises a vertical pole,
• wherein a transverse holding element extends from the vertical pole,
• wherein the at least one hovering platform is electrically connected to the at least one ground vehicle through a cable for transferring electrical power and data to the at least one hovering platform,
• wherein at least one of the vertical pole and the transverse holding element carries the cable,
• wherein the at least one hovering platform is flexibly held on at least one of the vertical pole and the transverse holding element through the cable or an additional component,
• wherein the at least one first inspection device is configured to determine a characteristic of the surface structure and to identify points of shape deviation by comparison with an intended characteristic, and
• wherein the system is configured for successively inspecting the surface structure through the at least one first inspection device and the at least one second inspection device being arranged in different heights at the same time.
