RES608 – 359 – MOD RESOLUTION 608 (REV.WRC-15) Use of the frequency band 1 215-1 300 MHz by systems of the radionavigation-satellite service (space-to-Earth) The World Radiocommunication Conference (Geneva, 2015), considering a) that WRC-2000 introduced a new allocation for the radionavigation-satellite service (RNSS) in the frequency band 1 260-1 300 MHz; b) that the frequency bands 1 215-1 240 MHz and 1 240-1 260 MHz were already allocated to the RNSS; c) that, in the frequency band 1 215-1 260 MHz, RNSS (space-to-Earth) systems have been successfully operating for more than 20 years without any reports of interference to the radars which operate in this frequency band; d) the importance of the continuing need for protection for the radiodetermination systems operating in the frequency band 1 215-1 300 MHz, noting a) Recommendation ITU-R M.1902 “Characteristics and protection criteria for receiving earth stations in the radionavigation-satellite service (space-to-Earth) operating in the frequency band 1 215-1 300 MHz”; b) Report ITU-R M.2284 “Compatibility of radionavigation-satellite service (space-to-Earth) systems and radars operating in the frequency band 1 215-1 300 MHz”, further noting that the provisions of No. 5.329 as adopted by WRC-03, will provide for the operation of the RNSS (space-to-Earth) in the frequency band 1 215-1 300 MHz and will protect the radiolocation systems operating in that frequency band, in addition to the protection already provided to radionavigation service systems operating in the countries listed in No. 5.331, recognizing 1 that ITU-R carried out studies related to the protection of the radiodetermination systems operating in the frequency band 1 215-1 300 MHz and that these studies should continue pursuant to relevant ITU-R Questions, such as Questions ITU-R 62/5 and ITU-R 217/4, so as to prepare, as appropriate, ITU-R Recommendations;
