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.
• APT supports upgrading to primary status with
  additional provisions to protect the
  (aeronautical) radionavigation service
• This supports the ICAO position

• Extending the EESS and the SRS into the band
  9300-9500 MHz.
• APT supports extending EESS and SRS into the band
  9300-9500 MHz on a primary status with additional
  provisions to protect the radionavigation service
• This supports the ICAO position

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)

• APT does not support an allocation for AMT in the
  band 5030-5091 MHz. This band remains protected
  for MLS.
• APT does support an allocation for AMT in the
  band 5091-5150 MHz.
• Allocation for AMT limited to flight testing
• Priority to be given to and AM(R)S allocation in
  the band 5091-5150 MHz
• This supports the ICAO position

8
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)

• APT does not support changes to current
  allocations in the band 108-112 MHz
• APT supports an allocation to AM(R)S in the band
  112-117.975 MHz.
• Compatibility with FM broadcasting required.
• This supports the ICAO position

9
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)

• APT supports an allocation to AM(R)S in the band
  960-1164 MHz.
• ICAO SARPs required.
• Protection to existing services and systems in
  this band
• This supports the ICAO position

10
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)

• APT supports an allocation to AM(R)S in the band
  5091-5150 MHz.
• APT does not support AM(R)S in the band 5030-5090
  MHz. This protects MLS
• APT does not support AM(R)S in the band 5000-5030
  MHz to protect RNSS

11
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)

• APT does not support any modification to current
  satellite allocations to for the modernization of
  civil aviation telecommunications systems.
• This does not support the ICAO position which is
  to include a Recommendation in the Radio
  Regulations on VSAT systems that can be used for
  aeronautical communications.

12
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.

• APT does not support any modification to the
  Table of frequency allocations in the 4-10 MHz
  band no changes to Appendix 27 are proposed.
• This supports the ICAO position.

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

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.
• No provisions proposed for unwanted emissions
  from RNSS systems in the band 1559-1610 MHz.
• This supports the ICAO position.

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
