The section’s technical expertise is system engineering of satellite-based telecommunication links. More specifically the section is responsible for the development of advanced Telecommunication systems, techniques and technologies for broadband, broadcast and mobile satcom applications as well as for Payload Data Transmission (PDT) communications.

The section provides technical support for the aforementioned expertise to many ESA projects and programs. Our main internal customer is however the Telecommunication and Integrated Application directorate. The section has an active and often lead role in standardisation bodies such as CCSDS, DVB, 3GPP and ETSI.
