Client: European Space Agency (ESA)

Mendoza, Argentina

The DS3 deep space antenna was designed and built for the European Space Agency (ESA) near Malargüe in the Argentine province of Mendoza. Together with the existing ones in New Norcia (Australia) and Cebreros (Ávila), it completes the reception system for signals from satellites exploring Mars, Venus and other planets in our Solar System.

The sensitivity of the electronic equipment designed by the Canadian company SED-Systems requires that the movements of the 35 m diameter antenna’s pedestal, made in Germany by Vertex Antennentechnik for wind of up to 80 km/h, do not exceed rotations of 1/82,500 radians, the equivalent of movements at the pedestal crown of 0.075 mm. The structure is designed to withstand wind of 180 km/h and seismic accelerations of 0.4 g.
