The development and realization of a European Data Relay System (EDRS) by the European Space Agency (ESA) in the frame of the ARTES 7 program, has settled a new standard for space based communication services with real-time and high-rate data relayed from Earth Orbiting (LEO) satellites and then transferred to the ground.
The dedicated EDRS-C Satellite will embark a Data Relay Payload including a Laser Communication Terminal (LCT) for the inter satellite link and a Ka-Band antenna for the data transfer link to the ground stations in Europe.
OHB SWEDEN CONTRIBUTION
OHB System has built the dedicated EDRS-C satellite on the basis of the SmallGeo platform with a considerable number of design improvements implemented. OHB Sweden, as a Core Team Partner in the Small GEO Telecom Satellite Programme is responsible for the attitude and orbit control subsystem on EDRS-C.
