The optical communication systems group develops – among other things – optical communication systems for aircraft and small satellites. Furthermore, it carries out measurement- and demonstration-campaigns, either with systems developed by DLR or in international cooperation. Therefore, the group operates the Optical Ground Station Oberpfaffenhofen (OGS-OP) as well as the Transportable Optical Ground Station.
Examples of systems that have been developed by the group are the Free-Space Experimental Laser Terminal II (FELT II), which has been tested aboard DLR’s Dornier 228 since 2008. Furthermore, within the project OSIRIS, optical communication systems that are optimized especially for small satellites are developed. In order to enable robust communication links, the group also deals with the development and implementation of Forward Error Correction (FEC) algorithms which are optimized for free-space optical communication links.
