Systematic Approach to Achieve Fine Pointing Requirement of SOLAR-B

Abstract The systematic approach adopted in SOLAR-B in order to achieve its fine pointing requirement is presented. The approach consists of : (1)unique pointing requirement analysis in frequency domain that provides a framework of satellite system design, (2)pointing performance analysis including attitude control, telescope pointing control, spacecraft dynamics, structural dynamics and telescope optics, (3)careful disturbance management both in frequency and time domain based on specially devised control parameters, and (4)elaborate tests such as microvibration transmissibility test using the structural model of the spacecraft with real and simulated disturbance sources and very sensitive inertial sensors.
