This is a map of sites used for research in radio astronomy. It is quite comprehensive but not every telescope is identified at every site. Sites that are not operated primarily for radio astronomy research are generally not included. Detailed information about site operations and the particulars of the telescopes at these sites can be found using the URLs given for the individual map locations. Summaries of the capabilities and frequencies of operation of some of the telescopes shown here are given on the web pages of the regional spectrum management bodies that operate on behalf of astronomy and the passive services Region 1 (Europe, Africa), http://www.craf.eu/raobs.htm Region 3 (Asia, Australia), http://www.atnf.csiro.au/rafcap/AP_RT.htm Some further information can be found at the http://www.IUCAF.org website as well The kml file used to generate this map can be downloaded on the map's page. It can also be read by Google Earth. If you have comments or questions, please contact Harvey S.
