their country name deleted from footnotes, if no
longer required, in accordance with Resolution 26
(Rev. WRC 97)

• Hungary proposes to be deleted from 5.362B
• Kuwait proposes to be deleted from 5.362B and

WRC-Agenda item 1.3In accordance with Resolution
747 (WRC-03) consider the upgrading of the
radiolocation service to primary allocation
status in the bands 9000 9200 MHz and 9300
9500 MHz and extending by up to 200 MHz the
existing primary allocations to the Earth
exploration-satellite service (active) and the
space research (active) in the band 9500 9800
MHz without placing undue constraints to the
service which the bands are allocated

• Upgrading radiolocation service to primary in
  9000-9200 MHz and 9300-9500 MHz.
• Broad support to the ICAO position (upgrading to
  primary status with additional provisions to
  protect the (aeronautical) radionavigation
  service)
• No support from CEPT and RCC for additional
  provision to protect the (aeronautical)
  radionavigation service.
• Also no support for additional provision from
  Russian Federation and Nigeria

9500 MHz and extending by up to 200 MHz the
existing primary allocations to the Earth
exploration-satellite service (active) and the

WRC-Agenda item 1.5To consider spectrum
requirements and possible additional spectrum
allocation for aeronautical telecommand and
high-bit rate aeronautical telemetry, in
accordance with Resolution 230 (WRC 03)

• All Regions and countries do not support an
  allocation for AMT in the band 5030-5091 MHz.
  This band remains protected for MLS.
• CEPT proposes to remove regulatory protection for
  MLS from the band 5091-5150 MHz.
• All Regions and Countries do support an
  allocation for AMT in the band 5091-5150 MHz.
• Allocation for AMT limited to flight testing in
  many proposals
• Priority to be given to an AM(R)S allocation in
  the band 5091-5150 MHz
• CEPT and USA proposals do not include precedence
  for AM(R)S over AMS (AMT) in the band 5091-5150
  MHz.

6
WRC-Agenda item 1.6 (1)To consider allocations
for the aeronautical mobile (R) service in parts
of the bands between 108 MHz to 6 GHz, in
accordance with Resolution 414 (WRC 03) and to
study current satellite frequency allocations
that will support the modernization of civil
aviation telecommunication systems, taking into
account Resolution 415 (WRC 03)

• Most proposals do not support changes to current
  allocations in the band 108-112 MHz
• Most proposals support an allocation for AM(R)S
  in the band 112-117.975 MHz (Nigeria and Senegal
  only in the band 116-117.975 MHz)
• Allocation limited to ICAO standard systems
• Compatibility with FM broadcasting required.
• CEPT does not accept use of 112-117.975 MHz as an
  extension to analogue voice

7
WRC-Agenda item 1.6 (2)To consider allocations
for the aeronautical mobile (R) service in parts
of the bands between 108 MHz to 6 GHz, in
accordance with Resolution 414 (WRC 03) and to
study current satellite frequency allocations
that will support the modernization of civil
aviation telecommunication systems, taking into
account Resolution 415 (WRC 03)

• Broad support for an allocation to AM(R)S in the
  band 960-1164 MHz.
• USA proposes AM(R)S only in the band 960-1024 MHz
  
• ICAO SARPs required.
• Protection to existing services and systems in
  this band

8
WRC-Agenda item 1.6 (3)To consider allocations
for the aeronautical mobile (R) service in parts
of the bands between 108 MHz to 6 GHz, in
accordance with Resolution 414 (WRC 03) and to
study current satellite frequency allocations
that will support the modernization of civil
aviation telecommunication systems, taking into
account Resolution 415 (WRC 03)

• No support for an allocation to AM(R)S in the
  band 5000-5030 MHz (Egypt, Mali and Cameroon
  support such an allocation)
• Broad support for an allocation to AM(R)S in the
  band 5091-5150 MHz.
• CEPT does not propose an allocation to AM(R)S
  (considers AM(R)S a sub-set of AMS)
• CEPT and USA do not support precedence of AM(R)S
  over AMS/AMT
• No support for AM(R)S in the band 5030-5090 MHz.
  This protects MLS

9
WRC-Agenda item 1.6 (4)and to study current
satellite frequency allocations that will support
the modernization of civil aviation
telecommunication systems, taking into account
Resolution 415 (WRC 03)

• No support for any modification to current
  satellite allocations for the modernization of
  civil aviation telecommunications systems.
• No support for inclusion of a Recommendation in
  the Radio Regulations on VSAT systems that can be
  used for aeronautical communications (except
  Cameroon and Mali).

10
WRC-Agenda item 1.13Taking into account
Resolutions 729 (WRC-97), 351 (WRC-03) and 544
(WRC-03) to review the allocations to all
services in the HF bands between 4 and 10 MHz,
excluding those allocations to service in the
frequency range 7000 7200 KHz and those bands
whose allotment plans are in Appendix 25, 26 and
27 and whose channeling arrangements are in
Appendix 17, taking into account the impact of
new modulation techniques, adaptive control
techniques and spectrum requirements for HF
broadcasting.

• No support to any modification to the Table of
  frequency allocations in the 4-10 MHz band that
  may affect Appendix 27 no changes to Appendix 27
  are proposed.
• This supports the ICAO position.

11
WRC-Agenda item 1.16To consider the regulatory
and operational provisions for maritime mobile
service identities (MMSIs) for equipment other
than shipborne mobile equipment taking into
account Resolution 344 (Rev. WRC-03) and 353
(WRC-03)

• Broad support to the provisions of ITU-R
  Recommendation M.585.3 and modifications to the
  Radio Regulations which extend the assignment of
  MMSI to aircraft stations and aids to navigation.
  
• This supports the ICAO position.

12
WRC-Agenda item 1.17To consider the results of
ITU-R studies on compatibility between the
fixed-satellite service and other services around
1.4 GHz, in accordance with Resolution 745
(WRC-03)

• All Regions/countries support the suppression of
  the secondary allocation for MSS feeder links in
  the bands 1390-1392 MHz and 1430-1432 MHz.
• This supports the ICAO position.

13
WRC-Agenda item 1.20To consider the results of
the studies and proposals for regulatory
measures, if appropriate, regarding the Earth
exploration-satellite service (passive) from
unwanted emissions of active services in
accordance with Resolution 738 (WRC-03)

• Most regions and countries do not support a
  measure that would adversely affect current radar
  operations in the band 1300-1400 MHz
• CEPT supports a limit to be included APT
  supports such a limit for new systems only.
• This may partly support the ICAO position
  proposed limit needs to be evaluated against
  radar characteristics

14
WRC-Agenda item 1.21To consider the results of
studies regarding the compatibility between the
radio astronomy service and the active space
services in accordance with Resolution 740 (Rev.
WRC-03), in order to review and update, if
appropriate, the tables of threshold levels used
for consultation that appear in the Annex to
Resolution 739 (WRC-03)

• APT is of the view that due to development in
  technology future RNSS systems can meet unwanted
  emissions criteria to protect RAS.
• Some Regions/countries support a fixed limit to
  protect RAS from unwanted emissions from RNSS
  systems in the band 1559-1610 MHz.

15
WRC-Agenda item 2To examine the revised ITU-R
Recommendations incorporated by reference in the
Radio Regulations communicated by the
Radiocommunication Assembly, in accordance with
Resolution 28 (Rev. WRC-03), and to decide
whether or not to update the corresponding
references in the Radio Regulations, in
accordance with principles contained in Annex to
Resolution 27 (Rev. WRC-03)

• No proposals from that appear to affect
  aeronautical services.
• This supports the ICAO position.

16
WRC-Agenda item 7.2To 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 802 (WRC-03)

• Support for inclusion of an agenda item for
  WRC-11 to address the MSS 1.5/1.6 GHz band to
  secure long term availability of spectrum for
  AMS(R)S.
• Little information available
