Preliminary Mission Analysis of Active Debris Removal Service for Large Constellations

In the recent years, many large constellations have been announced to be deployed in Low Earth Orbit. Together with the existing space debris, the failed satellites from large constellations will pose a severe safety threat to the space environment. Driven by the strong demand to remove the failed satellites, D-Orbit and Politecnico di Milano, participate in an ESA funded programme - Sunrise - as consortium to develop an Active Debris Removal service for large constellations. To cope with different mission scenarios, two mission architectures are proposed: mothership and chaser architecture. This paper will present the mission analysis of the two mission architectures for an OneWeb-like constellation. As a preliminary study, the orbit transfer phases, which dominate the prime cost drivers of ?v budget and mission time, as well as the drag-induced de-orbiting, will be presented.
