telescope1_type = 3-m radio telescopeThe Kölner Observatorium für SubMillimeter Astronomie (KOSMA) is a 3-m radio telescope located at 3,135 m on Gornergrat near Zermatt (Switzerland). It is operated by the [http://www.astro.uni-koeln.de/ I. Physikalisches Institut] (Cologne, Germany) and the [http://www.astro.uni-bonn.de/~webrai/ Radioastronomisches Institut] , University of Bonn. It is a submillimeter radio telescope that can be used for observations between 210 and 880 GHz.

Because of the good climatic conditions at the altitude of 3135 m (10285 ft), astronomical observatories have been located in both towers of the Kulmhotel at Gornergrat since 1967. In 1985, the KOSMA telescope was installed in the southern tower by the Universität zu Köln and, in the course of 1995, replaced by a new dish and mount. In the northern tower, a 1.5 m infrared telescope is operated by an Italian association of universities ( [http://www.arcetri.astro.it/irlab/ TIRGO] ).
