WRC -12 AGENDA ITEM 1.3
        ON UAS



        Presented by
        John Taylor




              Cairo
         19-20 Sept 2010
                    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




                         Cairo
                    19-20 Sept 2010
                       UAS
                   APPLICATIONS
• Two groups of UAS applications, anticipated fields of
  operation examples for each mission type




                                Cairo
                           19-20 Sept 2010
           AIRSPACE ISSUES

• 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



                         Cairo
                    19-20 Sept 2010
                Communication links
• 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




                                Cairo
                           19-20 Sept 2010
          Communication Links
• 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




                              Cairo
                         19-20 Sept 2010
        WRC-Agenda Item 1.3
• 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



                          Cairo
                     19-20 Sept 2010
        WRC-12 Agenda Item 1.3
       Resolution 421 Invites ITU-R
• 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

                             Cairo
                        19-20 Sept 2010
                WRC-12 Agenda Item 1.3
         Spectrum requirements and possible regulatory
    actions, including allocations, for safe operation of UAS
                            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 1.3

               ICAO 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.

       REGIONAL POSITIONS ON 1.3


• CITEL POSITION
• Support ITU‐R studies related to this agenda
  item, particularly on the amount of spectrum
  needed, frequency bands and
  compatibility with incumbent services.
• Supported by US, Canada and Brazil.

                WRC-12 Agenda Item 1.3

           REGIONAL POSITIONS ON 1.3
•   APG POSITION

• The current studies being carried out by ITU-R in WP 5B are supported.
• Allocations to AM(R)S, AMS(R)S and/or ARNS, in order to satisfy
  spectrum needs for UAS applications, are supported, preferably from
  existing aeronautical safety allocations.
• Compatibility with existing services, in particular ICAO standards based
  systems such as MLS, needs to be ensured.
• Due to the safety nature of UAS, regulatory provisions associated with
  the allocation need to be clear, unconditional and implement able in
  practice.
• AI 1.3 should be confined to safety communications and not payload
