ESA Science & Technology - The CHEOPS satellite in the Maxwell test facility

In September 2018, the CHEOPS satellite underwent acoustic noise testing and Electromagnetic Compatibility (EMC) testing at ESA's technical centre in the Netherlands. During EMC testing, the satellite was mounted on mechanical ground support equipment that allowed its attitude with respect to the test antennas to be varied. The foam pyramids distributed on the floor are arranged to absorb reflections from the metal mechanical ground support equipment (painted white). The successful tests have shown that the satellite is compatible with its electromagnetic environment at launch and in orbit.
