In 1964 the ESRO decided to create an independent test centre that would be part of ESTEC. The first building with vibration and thermal vacuum facilities (named F-building) was completed in 1966 and the first satellite to be tested was the ESRO-1 satellite in 1968. From the 1970s to the late 1980s the test centre was enlarged by following facilities: The Dynamic Test Chamber (DTC) in 1975, The Multishaker in 1983, The EMC facility in 1985, The Large Space simulator (by extending the DTC) in 1986, The Large European Acoustic Facility (LEAF) in 1989 and the Compact Payload Test Range (CPTR) in 1990.
