The German Space Operation Centre (GSOC) is presently involved in the preparation of two On-Orbit Servicing
Missions DEOS and OLEV which are presented in this paper. Additionally, we describe potential applications for
this mission including space debris removal. Since there are many new challenges in the context of Rendezvous &
Docking manoeuvres the ground segment design requires new concepts. We present our solutions in the field of
Approach Navigation and Teleoperation. Finally, an integrated system test including GSOC’s new European
Proximity Operations Simulator (EPOS) facility is described
