The SpacecraftLib library has been developed in Modelica for use in the domain of Systems Engineering for space systems with a special emphasis on modularity; usability and ease of modification and expansion. It is a multidisciplinary tool which combines all the relevant subsystems. Power; command and data handling; and mechanical models are integrated into a single Modelica device in order to model as completely as possible the behaviour of a physical onboard device. We will describe the tool; examine a case study and briefly analyze the results of a simulation.
