More Information
Summary:Occasionally, EMC support is needed also after the spacecraft is launched that allows to quantify the spacecraft's EMC performance in fully deployed configuration and validate EMC models that could not be validated by test before launch. In this paper, in-flight instrument data is utilised to validate an electric field interference prediction model that is based on on-ground measurements and 3D simulation data. The validated model can predict new interference scenarios for spacecraft configurations that cannot be replicated during cruise phase. The model can be also used to define unit level requirement that allows to control the noise at the source. The method is generic and can be adopted for various electric field instruments, frequency ranges or spacecrafts.
