Full Wave Simulation of Large Satellite for the Evaluation of Multiple Frequency Antennas Interference

The paper presents a full wave simulation of the spacecraft of JUICE, ESA’s Jupiter Icy moons Explorer mission. Results prove the possibility of simulating the entire spacecraft modelling the instruments of the payload in a realistic environment to predict unwanted interference and consequent unexpected RF behaviour that would be impossible to be foreseen by either stand-alone or simplified configuration of the antennas on board.

The simulations are performed making use of the new full wave analysis tool available in TICRA’s GRASP and show the capability of the software to deal with complex structures producing reliable results. The direct CAD import makes the tool very attractive in terms of modelling effort vs computational time.
