The Technologie-Erprobungs-Träger (TET) comprises the core element of the German Aero space Centre (DLR) 'On Orbit Verification' (OOV) program. The goal of the OOV program is to qualify new technological solutions for their application in space projects. The program serves to bridge the gap between the product tested and qualified on the ground and the utilization of the product in space. Here it is demonstrated that the product functions under on-orbit conditions which cannot or can only be partially simulated on the ground. TET is designed to be a modular and flexible micro-satellite for any orbit between 450 and 850 km altitude and inclination between 53 and SSO. With an overall mass of 120 kg TET is able to accommodate experiments of up to 50 kg. The first TET mission is scheduled to be launched together with a Russian weather satellite METEOR-2 on SOYUZ/FREGAT for autumn of 2010. The TET-1 satellite is launched as piggy-back in a LEO orbit. After LEOP and Commissioning the one year mission operation is controlled via the mission control centre in Oberpfaffenhofen. Payload data are stored in the payload data centre in Neustrelitz and can be retieved from the Experimenters via secured web access.
