A satellite on a given orbit around the earth must maintain contact to its earth ground stations. This requires a certain orientation of the satellite towards the earth, which must be re-established in case of deviations. Thus, a three joint manipulator arm mounted on the satellite should perform its transportation tasks in such a way, that the orientation of the satellite is maintained. If possible, a disorientation of the satellite should be corrected by tailored movements of the arm. In this case it is possible to cut down the tractability of the jet nozzles for the satellite's attitude control and to save mass and cost. If this is possible, which technical dimensions are necessary to solve this problem in a realistic way?
This problem statement has been announced by a space agency and you have to submit a project proposal which must compete with your competitors on the market!
You may start with a mass of 1940 kg for the satellite and a distance of 705 km to the earth.
