Abstract

The increasing usage of Internet, at home or at work, in fixed or mobile conditions, has triggered a strong demand for multimedia services through terrestrial communication networks and through satellite-based systems as well. Although the demand for satellite capacity has not been yet at the initially expected level, the satellite has started playing an active role in the market of access and interactive services.
Competition with terrestrial communication networks keeps progressing and gaining in variety at a sustained rhythm. Nevertheless satellite has valuable ubiquitous benefits: wide area coverage, rapid service deployment, efficient and cost effective complement to terrestrial infrastructures. Satellite is also a competitive offer for new infrastructures where terrestrial networks are absent, destroyed, scarce or too expensive to build. Satellite has a potential for implementing advanced technologies that could bring higher added values to multimedia services.
The absence of market forecast with a fair confidence beyond 5 years at best leads to an absence of trusted inputs that could define the satellite role and environment for the post 2015 period. However, it is possible to capitalize on technological expertise, and to project in this next age what could be the evolution the different techniques and technologies and what performances they can improve. This logic leads to the identification of likely trends, architectures and technologies that will be the basis of future broadband multimedia satellite systems after 2015.
The paper first analyses the foreseen trends in broadband networks. From these analyses, it identifies scenarios for the utilization of satellite and defines the corresponding performance requirements mainly in terms of capacity, ubiquity and flexibility. Then the paper describes an anticipated broadband satellite system over Europe and its key technologies. This will addresses transmission, access and networking techniques as well as the satellite payload and its technologies. This paper presents the main results of an ESA supported study (ARTES-1) and called Next Generation Broadband Satellite Systems (NGBSS).
