Cebreros station, DSA 2 (Deep Space Antenna 2), is located 77 kms west of Madrid, Spain. It hosts a 35-metre deep-space communications antenna, CEB, with X-band transmission and X- and Ka-Band reception.

CEB provides daily routine operations or back-up support for a range of deep-space with facilities for tracking, telemetry, telecommand and radiometric measurements (ranging, Doppler, meteo)

Estrack 35-m antennas are also equipped with Delta-DOR (Delta Differential One-Way Ranging) capability, a technology used to locate and track distant spacecraft incredibly precisely. CEB also hosts facilities enabling scientists to analyse received signals to perform radio science experiments.
