TDF 1 or TDF-1 was a French communications satellite which was to have been operated by Télévision de France (France Télécom). It was intended to be used to provide television broadcast services to Europe, however it failed before entering service. It was constructed by Aérospatiale, based on the Spacebus 300 satellite bus, and carried five Ku-band transponders. At launch it had a mass of 2,144 kg (4,727 lb), and an expected operational lifespan of eight years.[2]
