The CHEOPS satellite in the Maxwell test facility
The CHEOPS satellite during preparations for ElectroMagnetic Compatibility (EMC) testing in the Maxwell test facility at ESA's technical centre in the Netherlands.
The 12-meter-high anechoic chamber of the Maxwell test facility is particularly large. It was designed to accommodate the 10-metre-high Automated Transfer Vehicles (ATVs) used for carrying cargo to the International Space Station. The black wall behind CHEOPS is covered with high-power dissipation absorbers that are able to absorb satellite transmissions without overheating, so that auto compatibility tests, of whether a satellite's own emissions interfere with its other subsystems, can be performed in the absence of reflections.
