The work of thesis copes the specification of reusable software models and the realisation of a functional system simulator prototype for early design phases that covers all the physical aspects of a generic space mission, in order to reinforce the already well-established functional verification chain in space field. In particular the work is focused in the realisation and implementation of four generic models for the simulator prototype: Orbital model, Thermal model, Electrical power system model and Visibility model.
The models are realised through the study of the physical theory characterising the models. After a critical analysis, through physical assumptions which simplifies the mathematical problems behind the theory, it was possible to show the algorithms characterising the models. The following process is the creation of the architecture of the simulator through the use of flow charts and the SW implementation. The data provided by the simulator are in the end validated through the use of scenario testing.
