Case study

The French space agency brings
the digital mock-up in the white room to improve
the efficiency of assembly on satellites

Industry : Space

Founded in 1961, the Centre National d’Etudes Spatiales (CNES) is the government agency responsible for shaping and implementing France’s space policy in Europe.


• Efficiency of controls

• Improved quality 

• Traceability


The CNES (French National Centre for Space Studies) has been working for a long time with 3D digital model for the design of satellites in the engineering office. However operators in the whiteroom still work on paper plans for assembly and control tasks, which is time consuming and may lead to a risk of errors. How to ensure respect of production timing and quality during assembly operations on satellites?


  • Use of 2D paper plans to control conformity of part assembly
  • Long tedious inspection process
  • Risk of non-conformities not detected during assembly process


Quality control of parts assembly using comparison of the “as designed” from the 3D model to the “as built” on the real asset thanks to augmented reality and digital technology, using DiotaPlayer.

Results & Benefits

  • Faster and more complete inspection
  • Reduced risk of undetected non-conformities
  • Paperless process
