IGN YEBES 40m radio telescope Owned and operated by the National Geographical Institute (IGN) – National Astronomical Observatory (OAN) Currently member of the European VLBI Network (EVN) and International VLBI Service for Geodesy and Astrometry (IVS). Joining GMVA in 2011. Receivers in 2-115 GHz bands (Q band under construction). VLBI instrumentation (MK5B, DBBC, 1 Gbps fiber connection). Frequency agile (change in few minutes) More available at high frequencies. Jan 26, 2011 E. Ros - Yb and the HSA
