WRC-15 agenda item 1.13 Space Research Conclusion * towards a single solution: Remove the 5 km distance limitation for proximity operations by space vehicles communication with orbiting manned space vehicle, and not solely limit the use of the 410-420 MHz band by SRS (s-to-s) for extra-vehicular activities WRC-15 agenda item 1.14 UTC and leap seconds Feasibility of achieving a continuous reference timescale, conclusion * towards 4 possible options: Remove the leap second insertion or deletion from the UTC definition => contiguous time scale (retain UTC name or adopt a new name) Keep current UTC definition and disseminate both the UTC time-scale & a continuous time-scale on an equal basis; Keep current UTC definition but enable the recovery of the International Atomic Time (TAI) from the current implementation of UTC or use a continuous system time-scale. No change to the RR as results of studies are inconclusive Page 19 of 26 19

WRC-15 agenda item 1.5 Aeronautical Issue #1 (UAS in FSS) Unmanned Aircraft Systems Consider use of FSS bands (not App. 30/30A/30B) for control and non-payload communications (CNPC) of UAS in non-segregated airspaces. Different views were added on the analysis of the results of studies. Conclusion * towards 2 possible solutions: Identify conditions under which systems operating in the FSS could provide UA CNPC links; No change, on the basis of concerns about the ability of FSS to provide a safety service. WRC-15 agenda item 1.17 Aeronautical Issue #2 (WAIC) Spectrum requirements & regulatory actions, including appropriate aeronautical allocations, to support Wireless Avionics Intra- Communications (WAIC) Conclusion * towards a new P rimary allocation to the AM(R)S reserved exclusively for WAIC systems in the frequency band 4 200-4 400 MHz Page 20 of 26 20

GFT on WRC-15 agenda Aeronautical Issue #3 (Global flight tracking for civil aviation) (PP-14) resolves to instruct WRC-15, pursuant to No. 119 of the ITU Convention; to include in its agenda, as a matter of urgency, the consideration of global flight tracking, including, if appropriate, and consistent with ITU practices, various aspects of the matter, taking into account ITU-R studies, instructs the Secretary-General to bring this resolution to the attention of WRC-15 and ICAO, instructs the Director of the Radiocommunication Bureau to prepare a specific report on the matter as referred to in resolves above for consideration by WRC-15. ITU-R studies on-going within Working Parties 5B & 4C Two views included in Annex 1 of the CPM Report to WRC-15 WRC-15 agenda item 1.18 Automotive Radar Applications Conclusion * towards a P rimary allocation to the RLS in frequency band 77.5-78 GHz on a worldwide basis either: limited to automotive applications (with short range high resolution radars), OR supporting automotive radar operations Page 21 of 26 21

WRC-15 agenda item 1.15 Maritime Issue #1 (on board communication) Conclusion * towards a more efficient use of the existing frequencies in the range 450-470 MHz with the introduction of the possibility to use digital modulation and improved mitigation techniques. WRC-15 agenda item 1.16 Maritime Issues #2 (Automatic Identification System) Regulatory provisions & spectrum allocations to enable possible new Automatic Identification System (AIS) technology and other new applications to improve maritime radiocommunication Conclusion * towards different solutions with the goal to introduce a new concept called VHF data exchange system (VDES) with terrestrial and satellite components.
