Scope

The ITU Radiocommunication Assembly considering that, in order to ensure the efficiency of spectrum utilization, there is a need to assess the compatibility between the sound-broadcasting service in the band of about 87-108 MHz and the aeronautical radionavigation services in the band 108-118 MHz; that International Civil Aviation Organization (ICAO) Annex 10 (see Definitions in Annex 1, Appendix 2) does not specify the receiver interference immunity characteristics necessary to fully assess this compatibility; that the test procedures given in Annex 1 were used in the development of interference assessment criteria, appropriate to the ICAO Annex 10, 1998 receivers, as contained in Recommendation ITU-R SM.1009; that in order to refine the interference assessment criteria contained in Recommendation ITU-R SM.1009 additional tests are required on aeronautical radionavigation receivers designed to meet the ICAO Annex 10 interference immunity criteria; that there is a need for standardized test procedures.
