Radio astronomy service
Radio astronomy service (also: radio astronomy radiocommunication service) is – according to Article 1.58 of the International Telecommunication Union´s (ITU) Radio Regulations (RR)[1] – defined as «A radiocommunication service involving the use of radio astronomy.» Subject of this radiocommunication service is to receive radio waves transmitte by astronomical or celestical objects.

Frequency allocation
The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012).[2]
In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is with-in the responsibility of the appropriate national administration. The allocation might be primary, secondary, exclusive, and shared.
- primary allocation: is indicated by writing in capital letters (see example below)
- secondary allocation: is indicated by small letters
- exclusive or shared utilization: is within the responsibility of administrations
In line to the appropriate ITU Region the frequency bands are allocated (primary or secondary) to the radio astronomy service as follows.
