ABSTRACT<br />

The aim of this document is to present the control methodology applied all along a satellite<br />

development in order to guarantee the good behaviour of the satellite for Electromagnetic<br />

Compatibility concern (EMC).<br />

EMC MANAGEMENT AND ORGANISATION<br />

The EMC control activity is realised by an EMC specialised engineer who is integrated to the project<br />

team for all the duration of the program. He is responsible for the good performance of the satellite in<br />

term of Electromagnetic Compatibility.<br />

The typical satellite required performance is :<br />

• A self compatibility margin of at least 6 dB between the satellite emissions (RE&CE) and the<br />

susceptibility thresholds (20 dB for the pyrotechnic equipment’s)<br />

• A RF compatibility with the different launchers & launch pads in term of radiated emission and<br />

radiated susceptibility<br />

• A RF self compatibility between the payload and the others sub-systems.<br />

This implies a control of the following items :<br />

• respect of the EMC specification<br />

• respect of the electrical design rules<br />

• reliability of the design and validation by simulation if possible.<br />

The EMC philosophy in the satellite program is defined in the figure here-below :<br />
