The Centre Spatial de Liège (CSL) is an applied Research Center owned by the University of Liège, focused on design, integration and calibration of space observation instruments.
CSL also operated a highly specialized environmental test center to support ESA program as well as space industry and regional companies. Through several state of the art facilities standing in an ultra-clean environment, CSL provides a customized service to expose instruments, systems and even, satellites to extreme conditions encountered in deep space with a unique expertise in optics and thermal regulation, including cryogenics. We are proud to highlight our participation to a great number of renowned space missions such as SOHO-EIT, XMM, COROT, HERSCHEL, PLANCK, JUNO, etc.
CSL is an active research centre in the fields of space instruments, space testing and technologies. CSL is highly known as a test centre but it as also important activities in space instrumentation and advanced technologies. For years, the CSL has been an “ESA-coordinated facility”. Today, the Testing Department operates five thermal-vacuum chambers with volumes ranging from 1 to 170 m³, two shakers (88 to 200 kN) and a number of specialized equipments all located in a 1,000-m² clean room area (ISO 5 to ISO 7).
