Safran’s advanced optical ground support equipment chosen for IABG’s Space Test Center in Germany

Safran Reosc has been selected to design and produce the primary optical ground support equipment (OGSE) for the German company IABG’s (Industrieanlagen-Betriebsgesellschaft mbH) Space Test Center in Germany.

Composed of two off-axis collimator mirror assemblies and two flat mirror assemblies, this equipment will enhance the center’s capabilities and allow it to perform advanced performance tests on optical payloads for spacecraft.

The two off-axis collimator mirror assemblies and two flat mirror assemblies, each of which is tiltable, can test optical payloads up to 1,500mm in diameter with nanometer accuracy – 100,000 times finer than a human hair.

IABG’s Space Test Center is currently dedicated to mechanical qualification, electromagnetic compatibility and space simulation for payloads. By adding these new optical testing capabilities, it will have the resources needed to test future space-based Earth observation systems.

Safran Reosc has been working on this new optical ground support equipment since the spring of 2021. It will be used for the qualification, calibration and functional performance tests of electro-optical payloads. These new systems will perform high-precision optical measurements in a stringently controlled micro-vibration, thermal-vacuum and cleanliness environment.

Safran Reosc has built up extensive expertise in the design and production of optical ground support equipment, based on its recognized capabilities in optics manufacture and high-precision metrology. It’s the leading supplier of OGSE for some of today’s space nations (France, Japan, India and Taiwan).
