STENTOR (Satellite de Télécommunications pour Expérimenter les Nouvelles Technologies en Orbite) was a French communications satellite which was lost in a launch failure in 2002. Intended for operation by CNES, France Telecom, and Direction générale de l'armement (DGA). To validate, in flight, advanced technologies which would be integrated in the next generation of telecommunications spacecraft. It will also demonstrate new telecommunications services, including broadband and multimedia transmissions to small user terminals.[1]
