Therefore, satellite On-Orbit servicing (OOS) will be of great significance with regard to extend the satellite lifetime and increase its functionality or performance. Also the disposal of spacecrafts after their end of life will play a more and more important role in the future. The scenarios involve an on-orbit servicing spacecraft approach to a client satellite, capture or dock on it and take over the attitude and orbit control task of the coupled system. In the mated configuration the servicer can perform additional maintenance tasks. One of the critical issues of such a mission is to ensure a safe and reliable Rendezvous and Docking (RvD) process. For this most risky part of the mission new GNC-systems and robotic mechanisms must be developed and the entire RvD process has to be simulated and verified before the mission can be launched.In the last years many satellite projects started providing OOS capabilities. The German Aerospace Center (DLR) is involved in several projects developing key technologies for OOS missions and launched an own satellite project to demonstrate their OOS competence.The presentation provides an overview of the past activities and the ongoing OOS projects where DLR is involved. In the second part it focuses on the research activities concerning ongoing RvD developments and simulations.报告时间 (Time)：?? 2011年5月13日，14:00-16:00????????????????????????????????
