The Small Platform Programme (Small GEO) is developing a European platform product line for the market of smallgeostationary telecommunication satellites, with payload mass of 300 kg, 3 kW power and lifetime of 15 years.A core team of industries was formed, under the leadershipof OHB System, including Swedish Space Corporation,RUAG Space (CH, formerly Oerlikon Contraves Space) andLuxSpace (LU) to jointly define and develop a platform andto exploit commercially the resulting product.
Small GEO platform development
The Small GEO Platform Qualification Status Review (QSR)and PDR were held last year. Development at subsystemand unit level is progressing and will be valuable input for the review at system level. In parallel, development of critical technology, such as the High Efficiency Multiphase Thrusters (HEMPT) Electrical Propulsion System, is progressing. Thales Electronic Devices (DE) presented a new EM version with improved convergency of the beamplume, compatible with Small GEO needs.
Hispasat AG1 satellite development
This is a satellite that, in partnership with Hispasat (ES) will use the Small GEO platform developed by OHB and partners (e.g. CGS, Compagnia Generale per lo Spazio S.p.A.). Hispasat AG1 will be placed in a geostationary orbit, where it will supply Spain, Portugal, the Canary Islands and America with multimedia services. Hispasat will be integrating Hispasat AG1 in its existing fleet of geostationary communications satellites. This satellite will incorporate advanced payload technology such as a DVB S2 Processor and active radiating antenna. Hispasat is coordinating the activities of OHB, the prime contractor, focusing on the finalisation of the satellite sub-system design, payload accommodation and reviewof payload performance compliance with overall mission requirements and the overall satellite and systemrequirements. The mission and payload PDRs were completed in 2010.
Innovative Payload (REDSAT)
The System Onboard Processor (OBP) PDR was held in 2010. CDRs at unit level for the second element of the innovative payload, the Direct Radiating Array antenna,were completed in 2010 allowing industry to start the CDR at system level in January.Transparent Payload Manufacturing of most of the PFM/FM units started atthe end of 2010. CDRs for the remaining units will be completed within 2011.
Small GEO platform extension
The industrial team submitted its proposal to cover the areas where additional investments are envisaged toenable full commercial exploitation of the Small GEO platform. The ESA Tender Evaluation Board reviewed the proposal and negotiation with industry will start in 2011.
