Its target has an error of only six milligrams (which is ten times more accurate than the usual monitoring antennas of 15 meters in diameter). It has 250 temperature sensors distributed throughout the structure, so that it can auto-adjust automatically in case of expansion and contraction of the material due to meteorological changes.

Cebreros Station (also known as DSA 2 or Deep Space Antenna 2) is a European Space Agency, ESTRACK radio antenna station for communication with spacecraft, located about 10 km east of Cebreros and 90 km from Madrid, Spain, operated by the European Space Operations Centre and INTA. A 35-metre diameter antenna that receives and transmit in X- and Ka-bands is located at the site. Station code is "CEB". 20kW CW High Power Amplifier (HPA) it was created by Rheinmetall Italia SpA (Italy). The monitoring and control system was implemented by Microsis srl (Italy).
It provides daily support to Lisa Pathfinder, Mars Express and Gaia.[1]
It also provided support for Rosetta.
Two sister stations are New Norcia Station in Australia, and Malargüe Station in Argentina.
Until 2002, ESA lacked its own means to communicate with ships destined to other planets, or in very distant orbits and depended on NASA's network of listeners to receive the data collected by them.
