Thorny pyramids attached to the wall are located in the Hertz test chamber. They represent the infinite void of space.
This “anechoic” foam absorbs radio signals and allows radio frequency tests to be performed without distortion created by beating the signal from the walls of the chamber. In addition, it absorbs any sounds and makes this place an ideal location for solitary work.
Camera Hertz is located in the technical center of the Netherlands. This is an ionized room with metal walls, offering universal methods for measuring the radio frequency characteristics of an object. The walls block all external electromagnetic energy, such as television broadcasts and signals from mobile phones.
The remaining installations for radio frequency testing of ESA (also Maxwell’s camera for evaluating the EM compatibility of satellite systems) are covered with the same foam.
