The Wettzell telescope has been in operation since 1983 and was originally designed for satellite geodesy. It has made important contributions to the implementation and correction of global reference systems. Additionally, this telescope is used for VLBI observations worldwide. A new 13.2m TWIN radio telescope Wettzell pair (TTW1 and TTW2) are under construction to be included in the VGOS program.
