Steady State Emissions Modeling of Low Frequency Magnetic and Electric Fields Generated by GOCE CDMU

In this work, the test procedures and modeling results of low frequency (LF) electric and magnetic fields radiated by spacecraft equipment are implemented on near field measurements of the Command & Data Handling Management Unit (CDMU) of GOCE space mission. Specifically, the unit's LF electromagnetic signature is acquired up to 200 kHz and the frequencies that exhibit emissions are identified for both electric and magnetic field contributions. The measurements and modeling procedure are performed targeting to capture and characterize the steady state operation of the CDMU. The modeling methods presented in this work rely on measurements conducted in the frame of ESA's study on Pre-Verification of THOR Electro-Magnetic Cleanliness Approach.
