The receiver is located in the Cebreros ESA Deep Space tracking station in Avila, Spain.

History and evolution

The original Ashtech micro Z receiver was installed at the station in July 2005.

In December 2012 a Septentrio Polarx4 receiver was installed and a Septentrio Chokering MC antenna.


The receiver is located in the 35 meters antenna room of the station. A computer (with warm back-up) provides for the operation and remote control of the system.

The communications are carried out using the ESA permanent operational links.
