The preliminary design of Guidance, Navigation, and Control (GNC) algorithms andAttitude and Orbital Control Systems (AOCS) for spacecraft plays an important rolein the planning of a space mission. Many missions require accurate positioning andattitude control to be able to full the mission objectives. In an early phase of conceptualstudies, trade-os have to be made to the GNC/AOCS subsystem designand compromises with respect to other subsystem designs have to be taken intoaccount. This demands for the possibility of rapid prototyping where design parameters,such as the choice of sensors and actuators, can be changed easily to assessthe compliance to the mission requirements. This thesis presents the modelling ofGNC/AOCS components for a toolbox created in the MATLAB/Simulink environment.The resulting toolbox is a user-friendly tool, which simplies the creationof GNC/AOCS system simulations for conceptual studies. A number of completesimulations were constructed to demonstrate the capabilities of the toolbox.
