The purpose of this paper is to present a high fidelity simulation tool named “EMCASL” able to predict the disturbances conducted on the power bus of a spacecraft, and more generally, of any complex system. This advanced simulation tool handles the `conducted noise' electromagnetic compatibility among the various units and subsystems of the satellite and enables engineers to evaluate the effects of EMI on flight system, so that potential EMC problems can then be identified and solved in a timely manner. The system noise model is based on time and frequency domain equipment measurement in both differential and common mode and on appropriate behavioural modelling of any power conditioning and distribution units. The tool has been developed by Astrium Satellites and AxesSim in the frame of an ESA contract 22990/09/NL/GLC.
