  1. EUR RPS for WRC-12 preparation Preparations for WRC-12WRC -12 AGENDA ITEM 1.3 ON UAS Presented by John Taylor Paris 17-18 Mar 2011

  2. UAS • Unmanned Aircraft Systems (UAS) consists of Unmanned Aircraft (UA) and associated Control Stations. Unmanned aircraft are powered, aerial vehicles that do not carry a human pilot, use aerodynamic forces to provide vehicle lift, and may fly autonomously or be piloted remotely Paris 17-18 Mar 2011

  3. Two groups of UAS applications, anticipated fields of operationexamples for each mission type UASAPPLICATIONS Paris 17-18 Mar 2011

  4. UAS operations have been limited to segregated (restricted airspace) Advancements in design and technology Expanding deployment in a variety of roles More favorable in repetitive, routine, long duration operations Requirement for safe integration into non-segregated (non-restricted) airspace Integration into the Air Traffic Control system AIRSPACE ISSUES Paris 17-18 Mar 2011

  5. Integration into Air Traffic Control system and national airspace Operation in civil airspace with other air traffic Operation must be transparent to all other users as if UAS were a manned aircraft Requirement for communication links with UAS Three main types of communication links Command and Control link Relay of Air Traffic Control communications Relay of Sense and Avoid communications Communication links Paris 17-18 Mar 2011

  6. Seamless integration of UAS in civil airspace Requirement for maintaining safety of flight Requirement for short range line of sight communications Requirement for beyond line of sight communications The two types of communication requirements have a profound effect on the amount spectrum needed Hence WRC-07 placed and agenda item on the next WRC-12 to identify spectrum for UAS Communication Links Paris 17-18 Mar 2011

  7. to consider spectrum requirements and possible regulatory actions, including allocations, in order to support the safe operation of unmanned aircraft systems (UAS), based on the results of ITU‑R studies, in accordance with Resolution 421 (WRC‑07 WRC-Agenda Item 1.3 Paris 17-18 Mar 2011

  8. to conduct in time for WRC‑12 the necessary studies leading to technical, regulatory and operational recommendations to the Conference, enabling that Conference to decide on appropriate allocations for the operation of UAS that the studies referred to in invites ITU‑R 1 should include sharing and compatibility studies with services already having allocations in those bands to produce a report or a recommendation, as appropriate, on how to accommodate the radiocommunication requirements for UAS payloads WRC-12 Agenda Item 1.3Resolution 421 Invites ITU-R Paris 17-18 Mar 2011

  9. ISSUES What are the technical characteristics What are the protection requirements How much spectrum will be required Identification of current allocations that can accommodate UAS Identification of additional frequency allocations if required Ensuring compatibility with existing radiocommunication services What possible regulatory actions will be required by the Conference WRC-12 Agenda Item 1.3Spectrum requirements and possible regulatory actions, including allocations, for safe operation of UAS Paris 17-18 Mar 2011

  10. Work being undertaken in WP 5B Spectrum requirement identified 34 MHz terrestrial 56 MHz Satellite (including feeder links) ITU-RM.2171 (Doc. 5B/296 Annex 16) Framework towards DN Report ITU-R M.[UAS-BANDS] (Doc.5B/296 Annex 14) Draft CPM text (Doc. 5B/296 Annex 19) Work plan (Doc. 5B/296 Annex 18) WRC-12 Agenda Item 1.3Spectrum requirements and possible regulatory actions, including allocations, for safe operation of UAS Paris 17-18 Mar 2011

  11. Communications Scenario for line of sight Uplink : CS to UA 1. CS to UA Downlink : UA to CS 2. UA to CS UA Spectrum requirement LOS = 1+2 = 34 MHz 2 1 ATC Control Station WRC-12 Agenda Item 1.3Spectrum requirements and possible regulatory actions, including allocations, for safe operation of UAS Paris 17-18 Mar 2011

  12. Communication Scenario for beyond line of sight : Forward link 1. Uplink : CS to satellite 2. Downlink : satellite to UA Satellite Return link : 3. Uplink : UA to satellite Spectrum requirement 4. Downlink : satellite to CS 3 PILOT/SAT (UL+DL) = 1 + 4 = 28 MHz + 2 SAT/UA (UL+DL) = 2 + 3 = 28 MHz UAV 4 TOTAL BLOS = 2 x 28Hz = 56MHz 1 ATC CS WRC-12 Agenda Item 1.3Spectrum requirements and possible regulatory actions, including allocations, for safe operation of UAS Paris 17-18 Mar 2011

  13. Candidate frequency bands 960 –1 164 MHz 1 545–1 555 (space-to-Earth) and 1646.5–1656.5 MHz (Earth-to-space) 1610-1626.5 MHz (space-to-Earth and Earth-to-space) 5 000–5 150 MHz and 15.4-15.7 GHz WRC-12 Agenda Item 1.3Spectrum requirements and possible regulatory actions, including allocations, for safe operation of UAS Paris 17-18 Mar 2011

  14. Frequency Band Analysis 960 –1 164 MHz In-band systems Co-site compatibility Inter-site compatibility Existing adjacent band systems Potential future in-band systems WRC-12 Agenda Item 1.3 Paris 17-18 Mar 2011

  15. 1 545-1 555 MHz (space-to-Earth), 1 610-1 626.5 MHz (space-to-Earth and Earth-to-space), and 1 646.5-1 656.5 MHz (Earth-to-space) AMS(R)S allocation in portions of these bands Could be used for UAS communications links These bands also under study in WRC Agenda Item 1.7 UAS communications would need to be specified and standardized for use over satellite links RAS must be protected WRC-12 Agenda Item 1.3Frequency Band Analysis Paris 17-18 Mar 2011

  16. 5 000-5 150 MHz Suitable for UAS links AMS(R)S and AMRS allocations Need to protect MLS and RNSS Potential sub-band usage WRC-12 Agenda Item 1.3Frequency Band Analysis Paris 17-18 Mar 2011

  17. ITU-R M.2171, M.2204, M.2205 Draft new Reports ITU-R M.[UAS-Bands New Alloc] and ITU-R M.[UAS PERF and REQ] CPM-11 text has been published WRC-12 Agenda Item 1.3CURRENT STATUS OF WORK ITU-R Paris 17-18 Mar 2011

  18. WRC-12 Agenda Item 1.3ICAO POSITION ON 1.3 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.
