Paper Abstract

The SPICA mission aims to achieve high spatial resolution and unprecedented sensitivity in the mid to farinfrared wavelength astronomy. We derived a set of pointing requirements from SPICA's mission requirements. Disturbance management over the SPICA system and an implementation of isolators are necessary, because cryogenic coolers' disturbances could generate vibration. Alignment and random pointing errors for focal-plane instruments are reduced with a focal-plane guidance camera. Furthermore, an additional focal-plane camera and a tip-tilt mirror actuator are installed for coronagraph mode. This paper presents an overview of the SPICA pointing requirements and a feasibility study to achieve the requirements.
