**Agenda item 7.2**

7.2 To recommend to the Council items for inclusion in the agenda for
the next WRC, and to give its views on the preliminary agenda for the
subsequent conference and on possible agenda items for future
conferences, taking into account Resolution **803 (WRC-03)**

**Introduction**

The accommodation of unmanned aerial systems (UAS) will likely have
impact on overall aviation spectrum requirements. Though UAS have for
some time been used in segregated airspace where separation from other
air traffic can be assured, some administrations see requirements to
deploy them in non-segregated airspace. If UAS operate in non-segregated
civil airspace, they must be integrated safely and adhere to the same
operational practices as conventional manned aircraft. In addition to
the need for communications links between the UAS and the ground-based
air traffic control, the lack of a human onboard to monitor the aircraft
environment is a serious concern for the aviation community. As a
result, the aviation community is investigating various sense and avoid
systems to compensate for the loss of the onboard pilot. Many of these
sense and avoid systems envision the use of a radar or other
radiofrequency means to detect and track nearby aircraft, terrain, and
obstacles to navigation. As a result, additional aeronautical
radionavigation or other service spectrum may be required for a sense
and avoid system that will allow UAS to operate in non-segregated
airspace along side conventional manned aircraft.

The United States is submitting a draft resolution for the Preliminary
Agenda for the 2015 World Radiocommunication Conference that contains an
agenda item to address aeronautical radionavigation or other service
requirements to operate UAS in non-segregated airspace. The United
States is also submitting a related draft resolution that addresses what
additional spectrum may be required to support operation of UAS in
non-segregated airspace, and to determine how much and which bands
should be candidates for consideration.

**Proposal**

United States proposes to submit a new agenda item spectrum allocations
for use by unmanned aerial systems (UAS) with sense and avoid capability
to be considered at WRC-15, as shown in the attachment

RESOLUTION XXX

**Preliminary Agenda for the 2015 World Radiocommunication Conference**

**2.UAS** To consider spectrum requirements and possible additional
spectrum allocations in the radiodetermination service to support
operation of unmanned aerial systems (UAS) in non-segregated airspace,
in accordance with Resolution \[**USA-7\]**.

**Reasons**: Agenda Item 2.UAS is submitted as an agenda item for WRC-15
to enable the appropriate studies on the spectrum requirements for
Unmanned Aerial Systems (UAS).

DRAFT RESOLUTION \[USA-7\] (WRC-07)

**Consideration of spectrum allocations for use by unmanned aerial
systems (UAS) with sense and avoid capability**

The World Radiocommunication Conference (Geneva, 20XX),

considering

*a)* that world wide use of unmanned aerial systems (UAS) for use in
non-segregated airspace is expected to increase significantly in the
next 10 years;

*b)* that there is a possible need for additional aeronautical
radionavigation or other service spectrum to support the operation of
UAS in non-segregated airspace;

*c)* that there is a need to protect existing services,

recognizing

*a)* that there are emerging UAS applications, with plans to deploy them
in non-segregated airspace along side conventional manned aircraft where
they must be integrated safely and adhere to the same operational
practices as conventional manned aircraft;

*b)* that in order for UAS to operate in non-segregated airspace they
will require sense d avoid capability;

*c)* that future technologies and performance expectations for UAS will
require the use of spectrum to support the operation of the platform
including a means to sense the presence of nearby aircraft, identify
those aircraft where a collision risk exists and to provide situational
awareness data to the UAS control station so the UAS can avoid a
possible collision;

*d)* that due to the importance of ensuring the safe operation of UAS in
non-segregated airspace along side conventional manned aircraft, this
spectrum must be afforded special consideration as a safety service
according to No. **4.10** of the Radio Regulations (RR);

*e)* that studies will be required to provide a basis for considering
regulatory changes, including additional allocations, designed to
accommodate justified spectrum requirements of UAS with sense and avoid
capability consistent with the protection of incumbent services,

resolves

that WRC-15 consider regulatory requirements, including possible
additional primary spectrum allocations in the radiodetermination
service to support the operation of UAS in non-segregated airspace;

*invites the ITU-R*

1 to conduct, as a matter of urgency, studies to determine the spectrum
requirements to support a sense and avoid capability for deployment of
UAS in non-segregated airspace. These studies should consider existing
aeronautical allocations as well as potential new allocations;

2 that the studies referred to in *further resolves* 1 should include
sharing and compatibility studies with services already having
allocations in potential frequency bands identified in *further
resolves* 1,

*further invites*

all members of the Radiocommunication Sector and the International Civil
Aviation Organization (ICAO) to contribute to these studies.

**Reasons**: This resolution details the scope and required studies
related to future spectrum requirements of unmanned aerial systems'
sense and avoid systems. This resolution will enable the required
analysis to determine the spectrum requirements and potential frequency
bands to take place in the appropriate ITU-R Study Group(s).
