Abstract In 2011 the 20-m radio telescope at the Geodetic Observatory Wettzell, Germany contributed again very successfully to the IVS observing program. Technical changes, developments, improvements, and upgrades have been made to increase the reliability of the entire VLBI observing system. In parallel the mechanical assembly of the new Twin radio telescope (TTW) was finished while the HF-receiving system was constructed. The 20-m radio telescope inWettzell (RTW) is an essential component of the Geodetic Observatory Wettzell (GOW) and is jointly operated by Bundesamt f ur Kartographie und Geod asie (BKG) and Forschungseinrichtung Satellitengeod asie (FESG) of the Technische Universit at M unchen (Technical University Munich). In addition to the RTW, GOW also operates an ILRS laser ranging system, several IGS GPS permanent stations, a large laser gyroscope G (ringlaser), and the associated local techniques such as time and frequency, meteorology and super conducting gravity meter. Currently also the first fully VLBI2010-compliant Twin telescope is being built on location. It should extend the observation possibilities according to the new technical suggestions of the IVS Working Group 3 (WG3). Within the responsibility of the GOWare also the TIGO system in Concepcion, Chile, operated mainly together with the Universidad de Concepci on (see separate report about TIGO), and the German Antarctic Receiving Station (GARS) O Higgins in Antarctica, operated together with the German Space Center (DLR) and the Institute for Antarctic Research Chile (INACH) (see separate report about O Higgins).
