ACCESS Pointing Control System

ACCESS (Actively-Corrected Coronagraph for Exoplanet System Studies) was one of four medium-class exoplanet concepts selected for the NASA Astrophysics Strategic Mission Concept Study (ASMCS) program in 2008/2009 [14, 15]. The ACCESS study evaluated four major coronagraph concepts under a common space observatory. This paper describes the high precision pointing control system (PCS) baselined for this observatory.
