technology solutions it will investigate for C2 Links will be the use of FSS networks operating in the 14/12GHz and 30/20GHz frequency bands and that these SARPS will be adopted before WRC 23. During this investigation, ICAO will not only need to identify and include in its SARPs the technical characteristics for the space and earth stations, but also address both the Required Link Performance (RLP) and the effects of interference on the safety and efficiency of UAS/RPAS operations. This will require ICAO to be informed of the characteristic of the FSS networks and the interference environment in which they operate. Consequently, ICAO requests that ITU-R WP4A provide it with the following information in time for the commencement of FSS investigations in March 2017: ICAO’s The technical and operational characteristics of Unmanned Aircraft CNPC/C2 Links operated in the 14/12GHz and 30/20GHz frequency bands. See Appendix 1 for a detailed list of the requested Technical and Operational Characteristics and their corresponding ITU-R Recommendations/References. Any additional information and data covering topics such as regulation, operation and C2 Link performance that ITU-R has developed in its work on CNPC/C2 Links that ITU-R WP4A believes would help ICAO support their mutual responsibilities and timely ICAO’s release of SARPs.
