Satellite telecommunication and broadcasting systems have to adapt to the major evolutions introduced by the emergence of new multimedia services distributed by terrestrial networks. This major adaptation of satellite telecommunication systems implies the use of new technologies and standards, on-board satellites and within the telecommunication ground segment. The deeper interaction between space and ground infrastructures induced by these evolutions also leads to additional system complexity. The definition, design and end-to-end validation of these satellite networks require dedicated engineering tools and validation test beds running the major elements of the telecommunication mission, e.g. on-board and ground equipment implementing the various protocols and algorithms used in the system. Through two programmes called respectively "Atelier Télécom du Futur" and "Multimedia System Validation Test Beds", CNES has been developing since early 2000 an advanced simulation tool and complementary test beds to support engineering activities and cover most of the end-to-end validation needs of these new satellite telecommunication multimedia systems. This communication aims to present the technical objectives, the logic which has led to propose several complementary means, their main characteristics and development status. To end up, the first results provided by these tools and test beds are presented.
