In my thesis I introduce the ESA (European Space Agency) ESEO (European Student Earth Orbiter) LMP (Langmuir Probe) charge density sensor and its power supply which is developed in the Space Technology laboratory at the HVT (Department of Broadband Infocommunications and Electromagnetic Theory) department. Then I implement the EMC measurements described in the “Space engineering: Electromagnetic compatibility” of the common standards called ECSS (European Cooperation for Space Standardization). The execution of the measurements took place in the anechoic chamber of the HVT department, and in the Hungarian EMC laboratory of the Robert Bosch Ltd. in Budapest. My task is to make the LISN (Line Impedance Stabilisation Network) described in the ECSS standard, to design the EMC test layouts and perform the measurements for the LMP power supply model.

At the beginning I introduce the functional parts and purpose of the satellite, and the main parameters of the power supply model.

I introduce the basics of Electromagnetic Compatibility (EMC).

I present the steps for designing and checking of the LISN.

I introduce the designing, performing and the evaluation of the EMC measurements of the LMP power supply model.
