- Abstract
SGEO complements the European product portfolio of geostationary satellites in the area of telecommunication payloads in the range of 300 kg mass and up to 3 kW power. Based on the OHB-System programme LUX, which was supported by the DLR, the ESA ARTES-11 programme was initiated in 2005. The market analysis that was performed led to the conclusion, to further develop SGEO, a small and versatile platform for geostationary orbits, in order to be able to offer to the market a turnkey system with low investment risk for the customer and a short development time. Key design features are a high flexibility in order to accommodate a very wide range of future telecommunication missions, a short development time and the objective to build the system based on ITAR free subsystems and components. The system will provide a long lifetime of up to 15 years in orbit operations with high reliability. This paper provides an overview of the SGEO system key features and the ongoing development activities in the frame of the Artes 11 programme at ESA. A number of advanced and new technologies will be used in order to provide a competitive edge in the telecommunication market and, as a side effect, these new technologies can obtain the heritage expected by many customers and will be also used for the subsequent SGEO missions. On the other hand, the design of the first platform is largely based on existing well proven technology and relying strongly on the legacy from existing satellites. This balanced approach provides a competitive edge in the market now and with respect to the future product evolution. The SGEO product portfolio, ranging from satellite platform delivery up to in-orbit delivery of a turnkey system including satellite and ground control station, is designed to serve the commercial telecommunication market for applications in all frequency bands as well as optical laser communication. Applications considered include, but are not limited to Scalable Multimedia Ka-band, Hybrid-band, Data Relay and Ku-band TV-broadcast missions. The SGEO project will be realized by a consortium of European small and medium size system integrators under the lead of OHB-System. Further members of the consortium are Oerlikon Space AG (Switzerland), Swedish Space Corporation (Sweden) and LUXSpace Sarl (Luxembourg).
