Operations of On-Orbit Servicing Missions

Abstract

This chapter gives a comprehensive insight into the operational aspects of On-Orbit Servicing as well as rendezvous and docking missions. By means of several examples, the operational challenges are explained, and solutions are outlined. The orbit mechanics of a rendezvous mission is described in the local orbital frame. We use the Clohessy-Wiltshire equations to explain the different elements of the approach navigation. The influence of the sensor technology on the approach strategy is also discussed. In the context of robotic capture, we address the necessary changes in the communication concept, e.g., to ensure teleoperation. Finally, we describe the use of test and validation facilities for the critical maneuvers of a rendezvous and docking mission.
