Registration of Radio Astronomy Stations


Internationally, as well as in the U.S., the radio spectrum is divided into blocks, each of which is allocated to one or more of some forty radio services, defined in Article 1 of the Radio Regulations. Radio Astronomy is one of these radio services. In the U.S., a further distinction is made between spectrum used by the Federal Government and by non-federal entities, including state and local governments and the private sector. A block of spectrum may be allocated for shared government and non-government uses; reserved for use solely by the Federal Government or for use solely by non-government entities. Radio Astronomy allocations are always shared between the Federal Government and the non-government sector. Radio telescopes may be registered in the US, as well as internationally.
