The two main modules of the MetOp-FM2 satellite; the Payload Module, built by EADS Astrium in Friedichshafen (Germany) and the Service Module, built by EADS Astrium in Toulouse (France) were coupled together for the first time in July 2004.
Following this coupling the satellite has been subjected to tests to demonstrate the compatibility between the two modules and then to demonstrate correct functional behaviour at system level.
