RES155 – 238 – ADD RESOLUTION 155 (WRC-15) Regulatory provisions related to earth stations on board unmanned aircraft which operate with geostationary-satellite networks in the fixed-satellite service in certain frequency bands not subject to a Plan of Appendices 30, 30A and 30B for the control and non-payload communications of unmanned aircraft systems in non-segregated airspaces* The World Radiocommunication Conference (Geneva, 2015), considering a) that the operation of unmanned aircraft systems (UAS) requires reliable control and non-payload communication (CNPC) links, in particular to relay air traffic control communications and for the remote pilot to control the flight; b) that satellite networks may be used to provide CNPC links of UAS beyond the line-of-sight, as shown in Annex 1; c) that CNPC links between space stations and stations on board unmanned aircraft (UA) are proposed to be operated under this Resolution in the primary fixed-satellite service (FSS) in frequency bands shared with other primary services, including terrestrial services, however that would not preclude the use of other available allocations to accommodate this application, considering further that UAS CNPC links relate to the safe operation of UAS and have to comply with certain technical, operational and regulatory requirements, noting a) that this conference has adopted Resolution 156 on the use of earth stations in motion communicating with geostationary FSS space stations in the frequency bands 19.7-20.2 GHz and 29.5-30.0 GHz; b) that Report ITU-R M.2171 provides information on characteristics of UAS and spectrum requirements to support their safe operation in non-segregated airspace, _______________ * May also be used consistent with international standards and practices approved by the responsible civil aviation authority.
