EMC Characterization and Analysis of the Attitude Determination and Control System (ADCS) Board of a CubeSat Platform

This work explores the characterization and analysis of the electromagnetic emissions (EM) of the Attitude Determination and Control System (ADCS) board of a CubeSat developed at UNAM, using an EMxpert near-field scanner in the 150 kHz to 2.45 GHz range. The analysis is conducted in different operating modes, obtaining spectra and 3D spatial visualizations to identify critical emission areas. Regions of low and high electromagnetic emissions are identified. The obtained results will provide key factors to describe the electromagnetic behavior of the PCB under the operation modes of the subsystem. This work will be part of a broader analysis of EMC interference inside the CubeSat by evaluating all the boards that constitute the platform.
