Electromagnetic study of the power and radio boards of a student cubesat

In this paper we present an electromagnetic study of the picosatellite Robusta. The first step of this study consists in measuring the different high frequency signals emitted during normal operation by the power board and radiocommunication board. Both of them were amongst the most susceptible of all boards to radiate a high frequency field. The most radiating zones are thus determined. In a second step an electromagnetic interference is injected without contact on these boards, to make sure the different parts of the satellite will not disturb each other. We particularly focus on the susceptibility of the Radio Board (RB), because there is a risk that the antennas pick up some parasitic signals, which will propagate inside the RB.
