For the Earth from outer space: EDRS-C

The European "data highway in space" is on its way into geostationary orbit with technology from Jena.


The European Data Relay Satellite System EDRS was expanded  by a new satellite on August 6th 2018: EDRS-C was launched into space with an Ariane 5 rocket from the European Spaceport in Kourou (French Guyana).


Its services complement those of the European communications satellites Alphasat and EDRS-A. The satellite is OHB System AG's second communications satellite and is based on the SmallGEO satellite platform.


"We are pleased to contribute to the European Data Relay Satellite System EDRS with a dedicated satellite. With EDRS-C, we were able to extend the scope of our successfully deployed SmallGEO platform. We would like to thank Airbus Defence and Space for the trust placed in us," says Dr. Stefan Voegt, EDRS-C project manager at industrial prime contractor OHB System AG. "Our satellite meets the high requirements of the laser terminal supplied by TESAT for optical data transmission with high data rate. For this mission, we have expanded our modular TM/TC subsystem to include S- and Ka-band operation. In addition, encryption electronics ensure secure data transmission. We would like to thank our partners and suppliers for the good and successful cooperation".


The Thuringian space company Jena-Optronik GmbH was entrusted with the delivery of its successful ASTRO APS star sensors for the satellite's attitude and orbit control system (AOCS). OHB Sweden was responsible for the AOCS subsystem and as such was a direct customer of the Jena-based company.


"We were delighted to be able to continue our cooperation with the OHB team from the predecessor project SmallGEO. Successful space projects are created on the basis of a cooperative and trustful working atmosphere, the committed and goal-oriented approach of all participants coupled with a passion for the fascination of space travel," Sabine Ludwig, project manager at Jena-Optronik GmbH, explains. "When all this comes together - as in the case of EDRS-C - innovations from outer space can be jointly created for Earth."
