How to register a VGOS radio telescope at ITU and why it is important

VGOS radio telescopes enable observations in the range of 2-14 GHz and are much more receptive for unwanted radio frequency interference. Some space-borne transmitters may cause detrimental radiation to VGOS receivers. The registration of new VGOS sites at ITU is important to obtain administrative protection. This may help to avoid direct illumination by strong radars, as well as provide protection in the dedicated RAS bands from lower-level interference that degrades system sensitivity.
