## DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE

**Agenda Item 2:** to examine the revised ITU-R Recommendations
incorporated by reference in the Radio Regulations communicated by the
Radio 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
Resolution **27 (WRC-03)**;

**Background Information:** Agenda Item 1.15 of WRC-03 dealt with RNSS
matters as indicated in Resolutions **604 (WRC-2000)**, **605
(;WRC-2000)**, and Resolution **606 (WRC-2000)**.

Resolution **605** concerned the development and implementation of
regulations to provide protection for the ARNS in the band 1 164-1 215
MHz from all the emissions of "real" RNSS systems in the band. To this
end No. **5.328A** was adopted and is associated with the referenced
allocation. It states:

> **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-03)** 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
> **21.18** shall apply.

The language of this footnote regulation mandates that the RNSS in the
band 1 164-1 215, "shall" operate in accordance with the provisions of
Resolution **609 (WRC-03)**. This resolution is entitled: "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". Resolves 10 of this
mandatory Resolution states:

10. that the methodology and the reference worst-case ARNS system
    antenna contained in Recommendation ITU‑R M.1642 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,

As indicated the statement "shall be used" in relation to Recommendation
ITU-R 1642 clearly makes use of this recommendation mandatory in the
context of the Radio Regulations, and therefore must be considered part
of them.

Resolution **27** and its Annex set forth the criteria for
Recommendations and Resolutions to be: Incorporated by Reference".
Clearly, Recommendation M. 1642 meets these criteria.

As a consequence it is mandatory that this recommendation be considered
as part of Volume 4 of the Radio Regulations although it is not now.
Recommendation ITU-R 1642 must be included in subsequent revisions of
Volume 4 of the Radio Regulations.

It should be noted that a Working Party of the Special Committee has
come to the same conclusion regarding the incorporation in volume 4 of
the Radio Regulations of the referenced Recommendation as reflected in
the Attachment to Annex 15 of Document SC-WP/57-E.

**Proposal:**

USA/ /1 ADD

The Recommendation ITU-R M. 1642, " Methodology for Calculating the EPFD
Produced by All Space Stations within all RNSS systems and networks in
the band 1 164-1 215 MHz" is required to be added to Volume 4 , ITU-R
Recommendations incorporated by reference. A copy of Recommendation
ITU-R M. 1642 will be made available to the Conference in accordance
with the provisions of Annex 3 to Resolution **27**.

**Reason:** Recommendation ITU-R M. 1642 fulfills all of the criteria
for a recommendation which is incorporated by reference as set forth in
Resolution **27** and its Annex, and therefore must be included in
Volume 4 of the Radio Regulations.
