The European Data Relay System (DRS) which will be an essential component of the ESA In Orbit Infrastruture (IOI) which is planned to become operational in the late 1990s is considered. The DRS will offer communication and localization service capability to the user spacecraft operating in low orbit. The baseline design of the DRS at the end of the Data Relay Preparatory Program as emerged in the period from Spring 1990 to Spring 1991 is illustrated. The system requirements and the main system design criteria are described. The satellite essential concepts and elements, with particular attention to the payload, selected as the result of an effort of complexity minimization are also described. A summary of the results achieved in the definition of the DRS ground segment is given.
