The Yebes Observatory 40-m radio telescope

Yebes Observatory (OY) is the main scientific and technical facility and the headquarters of the National Centre for Radioastronomical Technologies and Geospace Applications (CNTRAG), which is run by the Spanish National Geographic Institute (IGN), a General Directorate in the Ministry of Development ("Fomento"). Yebes Observatory is classified as one of the scientific national facilities (Infraestructura Científico Técnica Singular, or ICTS) in Spain.

The 40-m radio telescope runs since 2008 as a member of the networks of Very Long Baseline Interferometry (VLBI) studies for astronomy (EVN, GMVA, etc) and geodesy (IVS), and more recently, as a single-dish facility for astronomical observations of cosmic sources.

The instrument is equipped with receivers in bands from 2 to 90 GHz, and appropriate backends. Access to scientists is made possible through a "Call for Proposals".
