1.3 in accordance with Resolution **747 (WRC‑03)**, consider upgrading
the radiolocation service to primary allocation status in the bands
9 000-9 200 MHz and 9 300-9 500 MHz and extending by up to 200 MHz the
existing primary allocations to the Earth exploration-satellite service
(EESS) (active) and the space research service (SRS) (active) in the
band 9 500-9 800 MHz without placing undue constraint on the services to
which the bands are allocated

sub-part 3a

Upgrading of radiolocation service in the bands 9 000-9 200 MHz and\
9 300-9 500 MHz

Introduction

WRC-07 Agenda item 1.3 invites the Conference to consider, *inter alia*,
the upgrading of the radiolocation service to primary allocation status
in the bands 9 000-9 200 MHz and 9 300‑9 500 MHz without placing undue
constraint on the services to which the bands are allocated.
Additionally ITU-R is invited to study, as a matter of urgency, the
relevant technical characteristics, protection criteria and other
factors.

The frequency band 9 000-9 200 MHz is currently allocated to the
aeronautical radionavigation service on a primary basis and to the
radiolocation service on a secondary basis. The frequency band
9 300-9 500 MHz is currently allocated to the radionavigation service on
a primary basis and to the radiolocation service on a secondary basis.

There is a need to provide contiguous spectrum in the 9 GHz bands for
the radiolocation service allocated on a primary basis worldwide, in
order to provide adequate spectrum for new radar systems to function.
There has been satisfactory coexistence for many decades, of various
radar systems in the bands 9 000-9 200 MHz and 9 300-9 500 MHz, which
include systems operating under the radionavigation and the
radiolocation service.

Description of the proposals:

Taking the above into account, together with the assessment requested by
Resolution 747 (WRC‑03), Europe proposes that:

a\) the radiolocation service in the bands 9 000-9 200 MHz and
9 300-9 500 MHz shall be upgraded to primary status;

b\) footnote No. 5.476 shall be suppressed.

**Reasons:** The frequency bands 9 000-9 200 MHz and 9 300-9 500 MHz are
allocated to the aeronautical radionavigation service and the
radionavigation service on a primary basis and to the radiolocation
service on a secondary basis. The radar systems operating in these
frequency bands under different services have similar characteristics
such as low-duty cycle emissions and scanning beams as well as
interference reduction techniques, considering further that current RNS
and RLS systems have been successfully operating in the 9 GHz range for
many years. ITU-R studies addressing other frequency bands indicated
that sharing in the bands 9 000-9 200 MHz and 9 300‑9 500 MHz between
the radionavigation and radiolocation services is feasible.

**5.476**

**Reasons:** Footnote No. 5.476 (in the band 9 300-9 320 MHz in the
radionavigation service, the use of shipborne radars, other than those
existing on 1 January 1976, is not permitted until 1 January 2001) is
obsolete and shall be deleted. The systems which were originally planned
to be introduced in this band are no longer in operation.

**SUP** EUR/10A3/3

RESOLUTION 747 (WRC-03)

Possible upgrade of the radiolocation service to primary allocation
status\
in the frequency bands 9 000-9 200 MHz and 9 300-9 500 MHz, and\
possible extension of the existing primary allocations to the Earth\
exploration-satellite service (active) and the space research\
service (active) in the band 9 500-9 800 MHz

**Reasons:** Consequential to the above proposals. The suppression of
the Resolution should be taken into consideration in conjunction with
the extension of the EESS (active) allocation at 9 GHz under the same
agenda item.

SUB-PART 3B

Further allocations to the Earth exploration-satellite service (active)
and the space research service (active) in addition to the band
9 500-9 800 MHz

Introduction

WRC-07 Agenda item 1.3 invites the Conference to consider, *inter alia*,
extending by up to 200 MHz the existing primary allocations to the Earth
exploration-satellite service (active) and the space research service
(active) without placing undue constraint on the services to which the
bands are allocated. Additionally ITU-R is invited to study, as a matter
of urgency, the relevant technical characteristics, protection criteria
and other factors.

The frequency band 9 500-9 800 MHz is currently allocated to the Earth
exploration-satellite service (active) and to the space research service
(active) worldwide on a primary basis. Since this band is well suited
for imaging applications and because technological progress today
provides the possibility to improve the features for a global monitoring
for environment and security, there is a need to increase the spectrum
available for the Earth exploration-satellite service (active) in this
part of the spectrum, for systems requiring larger bandwidth than the
current 300 MHz as in the 9 500‑9 800 MHz.

Description of the proposals:

Taking the above into account, together with the assessment requested by
Resolution 747 (WRC‑03), Europe proposes that:

a\) the band 9 300-9 500 MHz shall be allocated to the Earth
exploration-satellite service (active) and to the SRS (active) on a
primary basis indicating that this extension is limited to EESS (active)
and SRS (active) systems that need a band wider than the bandwidth
available between 9 500-9 800 MHz;

b\) the band 9 800-9 900 MHz shall additionally be allocated to the
Earth exploration-satellite service (active) and to the space research
service (active) on a primary basis, indicating that this extension is
limited to Earth exploration-satellite service (active) and space
research service (active) systems that need a bandwidth wider than the
bandwidth available within 9 300-9 800 MHz;

c\) footnote No. 5.476A shall be extended to cover also the bands
9 300-9 500 MHz and 9 800‑9 900 MHz and the footnote text shall be
modified accordingly;

d\) footnote No. 5.B03 shall be added in order to protect the fixed
service operating under No. 5.477 within the band 9 800-9 900 MHz.

**Reasons:** ITU-R studies to assess sharing possibilities between EESS
(active) and different types of radar used in the radionavigation and
the radiolocation services show that sharing is possible without
constraining the services to which the extension bands are allocated
already, at least in the case of wideband EESS (active) systems.
Mitigation techniques like those under study in ITU-R will further
improve the sharing situation. As SRS (active) systems are operated in
the vicinity of planets and celestial bodies or represent specific EESS
(active) systems under development, it is assessed that the extension of
300 MHz to the SRS (active) will not create any potential harmful
interference to other services in this band.

**5.A03** The use of the band 9 300-9 500 MHz by the Earth
exploration-satellite service (active) and space research service
(active) is complementary to the band 9 500-9 800 MHz and is limited to
systems that cannot be accommodated within the 9 500-9 800 MHz band and
that require bandwidths larger than 300 MHz. The use of the band
9 800-9 900 MHz by the Earth exploration-satellite service (active) and
space research service (active) is limited to systems that cannot be
accommodated within the 9 300-9 800 MHz band and that require bandwidths
larger than 500 MHz.

**Reasons**: Technical studies have considered SAR systems under the
EESS (active) and demonstrate that narrow-band systems present higher
interference potential compared to wideband systems extending over the
whole 9 300-9 800 MHz band. Acknowledging that the same conclusions
obviously apply to other EESS systems and recognizing further that
narrow-band EESS (active) systems can operate in the existing frequency
band (9 500-9 800 MHz), this proposal allows to provide adequate
bandwidth for wideband EESS (active) while ensuring maximum protection
to radiodetermination services allocated in the band. EESS (active)
systems, requiring even larger bandwidth than those which can be
accommodated in the band 9 300-9 800 MHz, would therefore further reduce
the risk of interference to radiolocation and radionavigation systems.
The band 9 800-10 000 MHz has alternatively been studied under
Resolution 747 (WRC-03) with similar results regarding radiolocation as
for the band 9 300-9 500 MHz. The fixed service, to which this band is
allocated, will also not be affected according to studies. However, the
concerns of some administrations with more extensive use of the FS
allocation should be accommodated as proposed in footnote No. 5.B03. As
SRS (active) systems are operated in the vicinity of planets and
celestial bodies or represent specific EESS (active) systems under
development, it is assessed that this extension of 300 MHz to the SRS
(active) will not create any potential harmful interference to other
services in this band.

**5.476A** In the band 9 300-9 900 MHz, stations in the Earth
exploration-satellite service (active) and space research service
(active) shall not cause harmful interference to, or constrain the use
and development of, stations of the radionavigation and radiolocation
services.      (WRC-07)

**Reasons**: The upgrade of the radiolocation service provides the same
regulatory protection to it over the whole tuning range and helps to
fulfil the requirements of radiolocation operations. The extension of
the EESS (active) allocation for SAR systems is required for the
enhancement of the resolution of images taken with these instruments or
the enlargement of the field of view of the Earth's surface, for global
environmental monitoring.

**ADD** EUR/10A3/9

**5.B03** In the band 9 800-9 900 MHz, stations in the Earth
exploration-satellite service (active) and space research service
(active) shall not claim protection from, nor cause harmful interference
to, stations of the fixed service operating under No. **5.477**.

**Reasons:** The band 9 800-10 000 MHz is allocated to the fixed service
on a secondary basis for all three ITU Regions. The band
9 800-10 000 MHz is allocated to the fixed service on a primary basis
for some countries by footnote No. 5.477. Footnote No. 5.B03, based on
the proposed note 5.FS included in the CPM text, defines a protection
requirement for the fixed service within the band 9 800-9 900 MHz, which
is an extension band for systems of the Earth exploration-satellite
service (active) and space research service (active) requiring a
bandwidth wider than 500 MHz.

RESOLUTION 747 (WRC-03)

Possible upgrade of the radiolocation service to primary allocation
status\
in the frequency bands 9 000-9 200 MHz and 9 300-9 500 MHz, and\
possible extension of the existing primary allocations to the Earth\
exploration-satellite service (active) and the space research\
service (active) in the band 9 500-9 800 MHz

**Reasons:** Consequential to the above proposals. The suppression of
the Resolution should be taken into consideration in conjunction with
the upgrade to primary status of the radiolocation service allocation at
9 GHz under the same agenda item.
