Geo-VLBI
Construction:
A dual band S/X receiver owned by Finnish Geospatial Research Institute. Constructed at TTI Norte, Santander, Spain. This receiver is used at Metsähovi for geodetic VLBI observations as well as spacecraft observation experiments. The receiver front end consists of cryogenic LNA's and a bulky feed system and polarizers at room temperature. This receiver needs a large subreflector (with diameter of 1.7 m) which is placed in the front of the original one, therefore simultaneous observations with mm-receivers are not possible.
