For over six decades the Airbus Defence and Space site of Stevenage in Hertfordshire has been the lynchpin for the development and construction of Telecommunications, Scientific, Earth Observation and Metrology Satellites, structures, propulsion systems, mechanisms and antennas. The Stevenage site has an AIT workforce of over 300 highly qualified and skilled employees who operate in some of the best equipped and state-of-the art development, assembly, test and production facilities in the space industry. The AIT facilities offer a comprehensive suite of manufacturing and test capabilities from piece part manufacture, construction of light weight honeycomb panel composites; CFRP filament wound composites, to full structure assembly, including propulsion, harness and thermal subsystems, to the assembly integration and test, of complex satellites in clean rooms of cleanliness class ISO 8. The Environmental test facilities include vibration, shock, thermal vacuum, climatic, static and high powered RF testing in vacuum to support the qualification of components, equipment’s, mechanisms and antennas. The extensive range of facilities provides customers with a ‘one stop’ test house capable of handling products from individual components (ADTMs / SADMs / Cryogenic Coolers) to spacecraft payloads (CSO Propulsion Module) and complete satellites (Clyde Space and SSTL). ADS services cover a variety of environmental simulation tests with the ability to meet bespoke monitoring requirements for the articles under test.
