Semi-Active Attitude Control and Off-line Attitude Determination for the SSETI-Express Student Micro-Satellite

摘要

This paper concerns the development of the Attitude Determination and Control System (ADCS) for the SSETI-Express micro-satellite mission. The mission is an educational project involving 14 universities and the European Space Agency (ESA). The satellite has been designed and built, by students, over a period of only 18 months. This paper emphasises on the trade-offs required to build an operational ADCS system within such a rapid developing project.
