On Modeling and Fault Tolerance of NanoSatellite Attitude Control System

The modeling of a satellite system and its orientation in space is a difficult and important step to define before controlling its attitude. Many methods have been developed since the first satellite was built. In this paper we propose a comparative study of the most important attitude representation methods adopted in the literature. We point out the advantages and disadvantages of each of these methods before choosing the one that suits our objective. Then we present, the Simulink blocks for Rotation angles method, which will be used in our attitude model. After that, we will present the implementation of this model in a system on chip, following the proposed architecture.
