IABG Space Systems Testing and Qualification Services
Europe's foremost independent space test centre — thermal-vacuum, vibration, acoustic, EMC, optical, and structural qualification for satellites and spacecraft, operating at IABG Ottobrunn and ESA ESTEC (via ETS joint venture).
Description
IABG's Space Systems Testing and Qualification Services provide satellite manufacturers, space agencies, and new-space companies with access to one of Europe's most comprehensive and independent environmental test infrastructure portfolios. Operating from its Space Centre at Ottobrunn/Taufkirchen near Munich — and through its joint-venture subsidiary European Test Services (ETS) at ESA's ESTEC facility in Noordwijk, Netherlands (a partnership with Airbus) — IABG supports every phase of spacecraft qualification from subsystem breadboard testing through full-satellite acceptance and proto-flight campaigns.
Thermal testing capabilities include thermal-vacuum chambers for space simulation, solar simulation, and high-temperature qualification. The flagship Phenix thermal-vacuum chamber at ESTEC (co-operated by ETS) features a 4 m diameter and 10 m usable length for large satellite platforms. Thermal-balance and thermal-cycling tests are performed under representative space vacuum conditions (<10⁻⁵ mbar), verifying thermal control system performance and supporting mathematical model correlation.
Mechanical qualification services encompass multi-axis vibration and shock testing, acoustic testing in diffuse-field reverberant chambers capable of noise levels up to 156 dB SPL, and seismic simulation for ground equipment. The Hydra vibration facility at ESTEC provides six-degree-of-freedom testing with a 20-tonne test table driven by 8 × 680 kN hydraulic actuators, accommodating the heaviest geostationary satellites. Experimental and operational modal analyses (EMA/OMA) characterize structural dynamic behavior and validate finite-element models.
IABG's newly opened Competence Centre Optics (CCO) is a state-of-the-art facility unique in Europe, purpose-built for testing and qualifying electro-optical satellite payloads — including Earth observation and reconnaissance instruments — under realistic space thermal and vacuum conditions, with high-precision optical metrology, a vibration-decoupled floor structure, and class-compliant cleanroom integration. Electromagnetic compatibility (EMC) testing, mass property determination (mass, center of gravity, moment of inertia), and material testing and failure analysis round out the portfolio. As a manufacturer-independent organization, IABG provides neutral test and verification services to ESA, DLR, Airbus Defence and Space, Thales Alenia Space, OHB, and a growing portfolio of new-space operators.
