The control system architecture and vibration mitigation approach for a Terrestrial Planet Finder (TPF) mission based on structurally connected interferometers are defined. The spacecraft configurations investigated and associated control and operational requirements are presented. Disturbance sources are identified and their relevance assessed. Results of dynamics analysis are presented, as well as a description of the dynamic models and simulations used to predict on-orbit performance. An assessment of the maturity of the technologies for control and vibration mitigation is provided. Analysis results indicate that pointing and path-length control requirements for a TPF mission based on structurally connected interferometers with baselines from 9 to 80 meters can be achieved using a conventional spacecraft attitude control system combined with active pointing and path-length control and a vibration mitigation approach that does not rely on structural damping.
