Technical Session VII: 13th Annual Frank J. Redd Student Scholarship Competition
Abstract
JAESat is a joint micro-satellite project between Queensland University of Technology (QUT), Australian Space Research Institute (ASRI) and other national and international partners including the Australian Cooperative Research Centre for Satellite Systems (CRCSS), Kayser-Threde GmbH, Aerospace Concepts and Auspace who will contribute to this project. The JAESat micro-satellite project is an educational and GNSS technology demonstration mission. The main objectives of the JAESat mission are the design and development of a micro-satellite in order to educate and train students and also to generate a platform in space for technology demonstration and conduction of research on a low-cost basis. The main payload on-board JAESat will be a GPS receiver called SPARx (SPace Applications Receiver), developed by the Queensland University of Technology for attitude and orbit determination. In addition to the GPS based attitude sensor, a star sensor will be on-board JAESat for attitude determination. JAESat will be three-axis stabilized based on a zero-momentum approach using magnetic coil actuators. This paper will outline the Attitude Control System (ACS) concept for JAESat including: subsystem configuration and components, performance requirements, control mode definition, attitude dynamic modeling, control law development, and attitude determination concept. Performance of the JAESat ACS is predicted via simulations using a comprehensive ACS model developed in Matlab Simulink.
