**Agenda item 2.0:**

To 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 the principles contained in the Annex to
Resolution 27 (Rev.WRC-03)

**Background information**

Although ITU-R Rec. M.1642 fulfilled the criteria for incorporation into
the RR in regulations agreed at WRC-03 no proposal recommended its
incorporation by reference and it was not entered in Volume 4 of the
RRs. A proposal to accomplish this is now contained in USA/2.0/1.
However, as a consequence of adopting such a proposal there are
consequential changes which need to be made in the RR, and a proposal is
required to indicate what these are. The proposal below is intended to
accomplish this objective

**Proposal:**

The United States proposes that the proposal USA/2.0/1 as found in
document CCP.II-RADIO/doc. 1403/07 rev.3 (p36) be augmented with the
addition of the texts found in the ANNEX to this document. These texts
indicate the consequential changes to the Radio Regulations which need
to be made when ITU-R Rec. M. 1642-1 is incorporated into the Radio
Regulations by reference.

**ANNEX**

**MOD** USA/2.0/2

**5.328A** Stations in the radionavigation-satellite service in the band
1 164-1 215 MHz shall operate in accordance with the provisions of
Resolution **609 (WRC‑07)** and shall not claim protection from stations
in the aeronautical radionavigation service in the band 960-1 215 MHz.
No. **5.43A** does not apply. The provisions of No. **21.18** shall
apply.     (WRC-03)

RESOLUTION 609 (WRC-07)

Protection of aeronautical radionavigation service systems from the
equivalent power flux-density produced by radionavigation-\
satellite service networks and systems in the\
1 164-1 215 MHz frequency band

5 that in order to allow multiple RNSS systems to operate in the
frequency band 1 164-1 215 MHz, no single RNSS system shall be permitted
to use up the entire interference allowance specified in *resolves *1
above in any 1 MHz of the 1 164-1 215 MHz band (see Recommendation **608
(WRC-07)**);

8 the administrations participating in the consultation meeting shall
designate one administration that shall communicate to the Bureau the
results of any aggregate sharing determinations made in application of
*resolves *2 above, without regard to whether such determinations result
in any modifications to the published characteristics of their
respective systems or networks (see Recommendation **608 (WRC-07)**);

9 that administrations operating or planning to operate ARNS systems in
the 1 164-1 215 10 that the methodology and the reference worst-case
ARNS system antenna contained in Recommendation ITU‑R M.1642-1 shall be
used by administrations for calculating the aggregate epfd produced by
all the space stations within all RNSS systems in the band
1 164-1 215 MHz, MHz band should participate, as appropriate, in
discussions and determinations relating to the *resolves* above;

2 to determine whether the pfd level in *recommends *1 of Recommendation
**608 (WRC‑07)** is exceeded by any subject space station, and to report
the findings of this determination to the participants in the
consultation meeting;

ANNEX TO RESOLUTION 609 (WRC-07)

Criteria for application of Resolution 609 (WRC-07)

RECOMMENDATION 608 (WRC-07)

Guidelines for consultation meetings established in\
Resolution 609 (WRC-07)

*c)* that this Conference revised this provisional limit and decided
that the level of ‑121.5 dB(W/m^2^) in any 1 MHz for the aggregate
equivalent pfd (epfd) applying for all the space stations within all
RNSS systems, taking into account the reference worst-case ARNS system
antenna characteristics described in Annex 2 of Recommendation
ITU‑R M.1642-1, is adequate to ensure the protection of the ARNS in the
band 1 164-1 215 MHz;

*d)* that this Conference decided that to achieve the objectives in
*resolves* 1 and 2 of Resolution **609** **(WRC‑07)**, administrations
operating or planning to operate RNSS systems will need to agree
cooperatively through consultation meetings to achieve the level of
protection for ARNS systems, and shall establish mechanisms to ensure
that all potential RNSS system operators are given full visibility of
the process but that only real systems are taken into account in the
calculation of the aggregate epfd,

recommends

1 that in the implementation of *resolves* 5 of Resolution **609**
**(WRC‑07)**, in the frequency band 1 164-1 215 MHz, the maximum pfd
produced at the surface of the Earth by emissions from a space station
in the RNSS, for all angles of arrival, should not exceed
‑129 dB(W/m^2^) in any 1 MHz band under free space propagation
conditions;

2 that the RNSS characteristics listed in the Annex 1, used when
applying the methodology contained in Recommendation ITU‑R M.1642-1, as
well as the calculated aggregate epfd in dB(W/m^2^) in each 1 MHz in the
range 1 164-1 215 MHz, should be made available in electronic format by
the consultation meetings.
