System Design and Control Aspect of a Novel Satellite Concept Panel Extension Satellite (PETSAT)

Abstract

A novel concept of satellite design, named “PETSAT,” is proposed and its system design and control aspect is discussed in this paper. In this concept, a satellite is made of several "Functional Panels" such as "Communication panel," "Attitude control panel," "Thruster panel," and “Mission Panel,” each of which has a special dedicated function. By connecting these panels by reliable connection mechanism in "plugin" fashion, the total integrated system as a whole has a satellite function. The satellite is configured by multiple panels with hinges, which poses unique problems on system design, information management and dynamics and control, such as design of function distributions into panels, inter-/intra-panel communication systems architecture, moment of inertia management, flexibility, distributed control and so on. The paper will describe the basic concept of PETSAT, result of system design and subsystem development with focus on information management system and Attitude Control Panel. In-orbit demonstration plan which is now scheduled in 2008 – 2009 will also be given.
