sub-part 6a

RESOLUTION 414 (WRC-03)

Consideration of the frequency range between 108 MHz and 6 GHz\
for new aeronautical applications

Introduction

1 In accordance with the Radio Regulations, the bands 108-117.975 MHz,
960‑1 164 MHz and 5 010-5 150 MHz are allocated on a primary basis to
the aeronautical radionavigation service in all ITU Regions.

2 According to footnote 5.328 the use of the band 960‑1 215 MHz by the
aeronautical radionavigation service is reserved on a worldwide basis
for the operation and development of airborne electronic aids to air
navigation and any directly associated ground-based facilities.

3 In accordance with footnote 5.444 the band 5 030-5 091 MHz is to be
used for the operation of the international standard system (microwave
landing system) for precision approach and landing. The requirements of
this system shall take precedence over other uses of this band.

4 In accordance with footnote 5.367, the bands 1 610-1 626.5 MHz and
5 000-5 150 MHz are also allocated to the aeronautical mobile-satellite
(R) service on a primary basis, subject to agreement obtained under
No. 9.21.

5 Results of ITU-R studies already performed with some non ICAO
standardized systems show that in the different bands listed in item 6
below, the sharing is feasible with these systems.

6 In response to Resolution 414 (WRC-03) Europe proposes three new
allocations (112‑117.975 MHz, 960-1 164 MHz and 5 091-5 150 MHz) for the
aeronautical mobile (R) service on a primary basis and limited to
systems that will operate in accordance with international aeronautical
standards under the conditions specified in Resolution 413 (WRC-07),
Resolution \[EUR/10A6/12 -- AM(R)S\] (WRC-07) and Resolution
\[EUR/10A6/13 -- AM(R)S 5 GHz\] (WRC‑07).

7 In response to Resolution 414 (WRC-03) Europe also proposes one new
allocation (5 091-5 150 MHz) for the aeronautical mobile service on a
primary basis and limited to aeronautical security applications under
the conditions specified in Resolution \[EUR/10A6/15 -- AMS(AS) 5 GHz\]
(WRC-07).

**5.A06** The use of the band 108-117.975 MHz by AM(R)S shall be in
accordance with Resolution **413 (WRC‑07)** and Resolution
**\[EUR/10A6/12 -- AM(R)S\] (WRC-07)**. The use of the band 108-112 MHz
by the AM(R)S is limited to systems that transmit navigational
information in support of air navigation and surveillance functions.
     (WRC-07)

**Reasons:** It is considered appropriate to indicate at an early stage
to the aeronautical community the availability of the frequency bands
112-117.975 MHz, for AM(R)S systems, in order to allow AM(R)S
development.

Studies have shown that there are sharing possibilities in the band
112-117.975 MHz which is already allocated for use by the aeronautical
radionavigation service and systems that transmit navigational
information in support of air navigation and surveillance functions.

The European Civil Aviation Conference (ECAC) long-term navigation
strategy foresees a diminishing role for the current VHF Omnidirectional
Radio Range (VOR) navigation aid in the band 112-117.975 MHz with
planned generalized deployment of the satellite-based navigation systems
and the emergence of economically affordable inertial navigation.
Accordingly it is anticipated there will be an opportunity to reallocate
spectrum in the aforementioned band to AM(R)S.

The frequency band 112-117.975 MHz by the AM(R)S shall not be used as an
extension band for the current analogue VHF voice communication system
operating in the band 117.975-137 MHz unless required to advance the
transition to the future communications system.

**5.328C** The use of the band 960-1 164 MHz by the aeronautical mobile
(R) service is limited to systems that operate in accordance with
recognized international aeronautical standards. Such use shall be in
accordance with Resolution **\[EUR/10A6/12 -- AM(R)S\]
(WRC-07)**.      (WRC-07)

**Reasons:** There is a need for additional allocation for long-range
aeronautical mobile (R) service applications for the development of an
aeronautical future radio system. This band is well suited for
components of the new aeronautical communication system. An allocation
of the whole band 960‑1 164 MHz would accommodate the AM(R)S spectrum
requirements as identified by ICAO (up to 60 MHz) providing more
flexibility for the implementation of the new system.

aeronautical mobile (R) service for the foreseeable future which may
accelerate due to the requirement to meet aviation objectives;

*f)* that these new allocations may be used for applications and
concepts in air traffic management which are data intensive; and which
may need to support data links that carry safety critical aeronautical
data;

*g)* that currently insufficient information is available about the
technologies which will be used, the amount of spectrum required, the
characteristics and sharing capabilities/conditions, and that therefore
studies are required with urgency on which AM(R)S systems will be used,
the amount of spectrum required, the characteristics and the conditions
for sharing with ICAO and non‑ICAO ARNS systems,

recognizing

*a)* that Resolution **114 (Rev.WRC‑03)** and Resolution **413
(WRC‑03)** require compatibility studies to be undertaken in the
relevant aeronautical bands;

-- the decisions made by the WRC-07 concerning the regulatory
provisions, including the allocations, applicable to the AM(R)S in order
to meet the requirements of these AM(R)S systems under development,

invites ITU-R

1 to study with urgency the AM(R)S systems which will be used, the
amount of spectrum required, the characteristics and the conditions for
sharing with ICAO and non-ICAO ARNS systems;

2 to continue studies in the bands 112-117.975 MHz, 960-1 164 MHz and
5 091‑5 150 MHz for use by new aeronautical applications in the
aeronautical mobile (R) service in order to determine how these can be
optimally accommodated in these bands without placing undue constraints
on services to which the frequency bands are additionally allocated;

3 to report to WRC-11 on the results of these studies,

further invites

1 ICAO to supply technical and operational criteria suitable for sharing
studies for new aeronautical systems;

2 ICAO to provide any sharing studies undertaken within ICAO between
ICAO standardized systems;

3 all members of the Radiocommunication Sector and especially ICAO to
contribute to these studies,

requests the Secretary-General

to bring this Resolution to the attention of ICAO.

**Reasons:**

1\) It is considered appropriate to indicate at an early stage to the
aeronautical community the availability of the frequency bands
112-117.975 MHz, 960-1164 MHz and 5 091-5 150 MHz for AM(R)S systems, in
order to allow the further technical developments and investments. Since
the technical characteristics and the sharing capabilities/conditions
applicable to such a new AM(R)S system are not known, it may be
necessary to specify during the development of these new systems some
further provisions relevant to these allocations. A resolution is the
best instrument to do this: a resolution can invite future conferences
to consider the developments, and at the same time it may include the
provisions deemed necessary at certain stages of development or
introduction of such new systems.

2\) The Resolution limits the use of the new allocations to systems
which have proven compatibility with systems operated in the
radionavigation service.

2 that prior to operating in the frequency band 5 091-5 150 MHz any
AM(R)S systems shall meet SARPs requirements published in Annex 10 of
the ICAO Convention on International Civil Aviation, and that those
requirements will ensure, consistent with appropriate ITU-R
Recommendations, compatibility with FSS systems operating in that band;

3 that studies of the band 5 091-5 150 MHz be undertaken by ITU-R
regarding the apportioning of the FSS 3% Δ*T*/*T* aggregate interference
limit between new AMS allocated at this Conference, with the task of
developing or revising Recommendation ITU-R M.\[AM(R)S/AS 5 091-5 150
MHz\] to ensure that aggregate limit is not exceeded;

4 that until the studies in *resolves* 4 are completed, stations in the
AM(R)S, shall be designed in such a manner that the maximum EIRP applied
to any station of an AM(R)S network be limited to the following EIRP
mask:

$\text{EIRP}_{\text{max}}(\theta)\  = 4\text{.}6 + \ \text{max}\left\lbrack G_{1}(\theta),G_{2}(\theta) \right\rbrack - \text{10} \times \text{log}\text{10}\left( \frac{1\text{.}\text{23}}{\text{Bt}} \right)$

where:

*EIRP~max~*() : AM(R)S station maximum EIRP (dBW/1.23 MHz)

*Bt*: AM(R)S station transmitted bandwidth (MHz)

 : Absolute value of the elevation angle relative to the angle of
maximum gain (degrees).

This EIRP mask will be reviewed at a future conference preferably
WRC-10,

invites

administrations and ICAO to supply technical and operational criteria
necessary for sharing studies for the aeronautical mobile (R) service,
and to participate actively in such studies,

instructs the Secretary-General

to bring this Resolution to the attention of ICAO.

**Reasons:** The Resolution limits the use of the new allocations to
systems in accordance with ICAO standards. Compatibility studies between
standardized ICAO systems are under the responsibility of ICAO.

DRAFT RESOLUTION \[EUR/10A6/15 -- AMS(AS) 5 GHz\] (WRC-07)

Considerations for sharing the band 5 091-5 150 MHz by the aeronautical
mobile service for aeronautical security applications\
and the fixed-satellite service

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* the current allocation of the 5 091-5 150 MHz band to the
fixed-satellite (FSS) (Earth-to-space), which is limited to feeder links
of non-geostationary-satellite (non-GSO) systems in the mobile-satellite
service (MSS) services;

*b)* the current allocation of the frequency band 5 000-5 150 MHz to the
aeronautical mobile satellite (R) service (AMS(R)S) is subject to
agreement obtained under No. **9.21** and the aeronautical
radionavigation service (ARNS);

*c)* this Conference has allocated the 5 091-5 150 MHz band for the
aeronautical mobile (R) service (AM(R)S);

*d)* this Conference has allocated the 5 091-5 150 MHz band for the
aeronautical mobile service (AMS) limited to secure and confidential
communications between aircraft and ground, principally during unlawful
interruption to aircraft operations,

recognizing

*a)* that precedence is to be given to the microwave landing system
(MLS) in accordance with No. **5.444** in the frequency band 5 030-5 091
MHz;

*b)* that Resolution **114 (WRC-03)** applies to the sharing conditions
between the FSS and ARNS in the 5 091-5 150 MHz band;

*c)* that Resolution **\[EUR/10A6/13 -- AM(R)S 5 GHz\]** provides
guidance on the use of the band 5 091-5 150 MHz by the AMS,

noting

that ITU-R studies describe methods for ensuring compatibility between
the AMS for aeronautical security applications and FSS operating in the
band 5 091-5 150 MHz,

resolves

1 that the AMS is limited to stations providing secure and confidential
radiocommunications intended for systems used in response to unlawful
interruption of aircraft operations;

2 that studies of the band 5 091-5 150 MHz be undertaken by the ITU-R
regarding the apportioning of the FSS 3% Δ*T*/*T* aggregate interference
limit between new AMS allocated at this Conference, with the task of
developing or revising Recommendation ITU-R M.\[AM(R)S/AS 5 091-5 150
MHz\] to ensure that aggregate limit is not exceeded;

3 until the studies in *resolves* 2 are completed, stations in the AMS,
limited to aeronautical security applications, shall be designed in such
a manner that the transmitter power flux-density be limited to --140.25
dBW/(m^2^ · 1.23 MHz) at an FSS satellite using full Earth

coverage receive antennas with an orbit of 1 414 km. This value will be
reviewed at a future conference, preferably WRC-11;

4 that administrations, in making assignments, shall ensure that the
requirements for the AM(R)S take precedence over those of the AMS for
security applications.

**Reasons:**

1\) There are many instances of unlawful interruptions to aircraft
operations ranging from passenger air rage to hijacking. Every
interruption requires intervention from the appropriate government
authorities. Since the terrorist attack of 11 September 2001 there has
been a significant increase in security measures for civil aviation, but
even these have not eradicated air rage or even hijacking.

2\) One requirement foreseen is the need to have cost-effective
confidential communications between aircraft and ground that can handle
voice, data and video information. This would provide decision-makers
with accurate and timely situation awareness.

3\) Flight trials using adapted IMT 2000 technology have demonstrated
that propagation in the band 5 091-5 150 MHz provides acceptable
performance for this purpose. The initial requirement for bandwidth is
15 MHz.

4\) The band 5 091-5 150 MHz already has allocations for ARNS and FSS.
Studies have concluded that sharing with ARNS (MLS) and FSS, and the
proposed new allocations for AM(R)S and AMT (5 GHz), can be achieved.
However, it is recognized that the FSS transmissions will cause
intermittent interference in certain areas but the design of
applications can provide adequate mitigation.

RESOLUTION 415 (WRC-03)

Study of current satellite frequency allocations that will\
support the modernization of civil aviation\
telecommunication systems

Introduction

Resolution 415 sought to study the broadening of frequency allocations
to allow expansion of the ICAO CNS/ATM systems. The studies reviewed
ground-ground and ground-air communications.

Studies have not identified the need for any regulatory changes at this
time and therefore no changes to the Radio Regulations are required as
part of WRC-07 Agenda item 1.6, Resolution 415.
