The purpose of this Report is to give examples of technical characteristics for the UAS CNPC links in certain frequency bands. But no technical studies have been done in these frequency bands For BLOS requirements : Candidate frequency bands (2/2)

17 Direction générale de lAviation civile Direction des Services de la Navigation Aérienne 6-7th October 2011 CPM-11 report has been published 7 methods are proposed to satisfy this agenda item: 5 methods for the satellite component 1 method for the terrestrial component 1 method, covering both terrestrial and satellite components All the allocations have to be used in such a way that the systems envisaged for UAS control and non- payload radiocommunications comply with ICAO SARPs Any method or a combination of these methods described in the CPM-11 report may be used. Possible regulatory actions (1/3)

18 Direction générale de lAviation civile Direction des Services de la Navigation Aérienne 6-7th October 2011 Method B proposes new AM(R)S allocations for the terrestrial component. Method C proposes no change to the Table of Frequency Allocations (RR Article 5) for frequency bands for which the studies have not been completed (for both terrestrial and satellite components, ). Possible regulatory actions (2/3)

19 Direction générale de lAviation civile Direction des Services de la Navigation Aérienne 6-7th October 2011 Five methods for the satellite component: Method A1 proposes the use of the current AMS(R)S allocations for both links (unmanned aircraft to satellite and unmanned aircraft control station (mobile and fixed) to satellite); Method A2 proposes the use of the current MSS, AMSS and AMS(R)S allocations for both links (unmanned aircraft to satellite and unmanned aircraft control station (mobile and fixed) to satellite) and FSS allocations (only for the fixed unmanned aircraft control station to satellite link) in accordance with the Radio Regulations; Method A3 proposes the use of the current FSS allocations by adding a new footnote pointing toward a WRC Resolution/Recommendation (except frequency bands covered by Appendices 30, 30A and 30B to the Radio Regulations); Method A4 proposes to restrict the communication link between unmanned aircraft and satellite to AMS(R)S allocations, to confirm the use of AMS(R)S allocations for the radiocommunication link between unmanned aircraft control station and the satellite and to allow the use of the FSS allocations for this link (except frequency bands covered by Appendices 30, 30A and 30B to the Radio Regulations); Method A5 proposes new AMS(R)S allocations. Possible regulatory actions (3/3)

20 Direction générale de lAviation civile Direction des Services de la Navigation Aérienne 6-7th October 2011 Introduction of UAS into non-segregated airspace must not reduce the current level of safety ITU regulations provide special measures for the protection of safety communications Those special measures are applicable to the AM(R)S, AMS(R)S and ARNS allocations used by all ICAO standardized C/N/S systems Such measures are not applicable to other non-safety allocations, in particular to FSS, and consequently such allocations cannot be used for UAS without affecting the level of safety Protected Spectrum, why?

21 Direction générale de lAviation civile Direction des Services de la Navigation Aérienne 6-7th October 2011 Uncertain jurisdiction and responsibility for interference mitigation Special measures in ITU Radio Regulations cannot be used for protection and interference mitigation In a shared frequency allocation scenario, uncertain priority of access to UAS control Majority of FSS allocations are not fully co-ordinated. In case incompatible assignments are made in two separate States, then UAS control is not afforded any protection against interference In case of interference resolution, the UAS control service may be treated equally or lower than a television broadcast service Potential Interference UAS control Service regulated by State A Service regulated by State C Unmanned Aircraft flying over territory of State B Examples of risks using non-safety frequency allocations for satellite communications with UAS

22 Direction générale de lAviation civile Direction des Services de la Navigation Aérienne 6-7th October 2011 ICAO position To support, based on the results of studies identified in Resolution 421, any modification to existing allocations, or new allocations required to accommodate UAS operations in non- segregated airspace while maintaining the safety and regularity of flight of all types of aircraft. Accordingly, to ensure that allocations used, in particular, for UAS command and control, ATC relay and sense and avoid in non- segregated airspace are in the AM(R)S, AMS(R)S and/or ARNS and do not adversely affect existing aeronautical systems To oppose the use of this agenda item to seek new spectrum allocations to meet payload requirements.
