RES418 – 316 – MOD RESOLUTION 418 (REV.WRC-15) Use of the frequency band 5 091-5 250 MHz by the aeronautical mobile service for telemetry applications The World Radiocommunication Conference (Geneva, 2015), considering a) that there is a need to provide global spectrum to the mobile service for wideband aeronautical telemetry systems; b) that the operation of aircraft stations is subject to national and international rules and regulations; c) that the frequency band 5 030-5 150 MHz is allocated to the aeronautical radionavigation service on a primary basis; d) that the allocation of the frequency band 5 091-5 250 MHz to the fixed-satellite service (Earth-to-space) is limited to feeder links of non-geostationary satellite systems in the mobile-satellite service; e) that the frequency band 5 091-5 150 MHz is also allocated to the aeronautical mobile-satellite (R) service on a primary basis, subject to agreement obtained under No. 9.21; f) that WRC-07 allocated the frequency band 5 091-5 150 MHz to the aeronautical mobile service on a primary basis subject to No. 5.444B; g) that the frequency band 5 150-5 250 MHz is also allocated to the mobile, except aeronautical mobile, service on a primary basis; h) that WRC-07 additionally allocated the frequency band 5 150-5 250 MHz to the aeronautical mobile service on a primary basis, subject to No. 5.446C; i) that aeronautical mobile telemetry (AMT) in the aeronautical mobile service is not considered an application of a safety service as defined in No. 1.59, noting a) that results of studies show the feasibility of using the frequency band 5 091-5 250 MHz for the aeronautical mobile service on a primary basis, limited to transmissions of telemetry for flight testing, under certain conditions and arrangements; b) that the identification by ITU-R of technical and operational requirements for aircraft stations operating in the frequency band 5 091-5 250 MHz should prevent unacceptable interference to other services; c) that the frequency band 5 091-5 150 MHz is to be used for the operation of the international standard microwave landing system (MLS) for precision approach and landing;
