Madrid Deep Space Communications Complex Activity · Robledo de Chavela, Sierra Oeste, Madrid The Madrid Deep Space Communications Complex is a station of the Deep Space Network born of a Spanish-American agreement of 1964 and operational since July 1965, run by the National Institute for Aerospace Technology as part of the bilateral cooperation with NASA. It combines the 70-metre DSS-63 antenna with several 34-metre ones, and tracks probes such as the Voyagers or Cassini. It is one of the network's three sites, together with the complexes at Goldstone, California, and Canberra, Australia, and it also supports radio astronomy and very-long-baseline interferometry, including its participation in the European VLBI Network.
