Electromagnetic Emission of Pulsed Plasma Thrusters

This paper deals with the measurement of characteristics of electromagnetic emission of electric propulsions as applied to the EMC problems. Electric propulsion systems on the basis of pulsed plasma thrusters, which are used for the orbit correction of small satellites, are considered as the sources of unintended noise of artificial origin. Test results for the spectral characteristics of emission for the PPT model with the discharge energy of 50 J obtained under ground conditions and their discussion are presented in this paper.
