This presentation deals with data relay systems and describes a S-band user terminal being developed for the DRS european system. The interest of DRS is briefly reminded and the need for spectrum spreading evoked before the antenna trade-off is assessed. The topics which are aimed for this terminal are listed; the major items are described, essentially the SS transponder. Special features of applications like SPOT 4 and HERMES are highlighted and some future possible evolutions are eventually addressed.
