Mr. Donald Abelson

Chief of the International Bureau

Federal Communications Commission

Washington, D.C. 20554

Dear Mr. Abelson:

The National Telecommunications and Information Administration on behalf
of the Executive Branch Agencies, has approved the release of additional
proposals for WRC-2000. These proposals are being forwarded to you for
review. Karl Nebbia from my staff will contact Damon Ladson and
reconcile any differences.

Enclosed, originated by the federal agencies, are new draft proposals
for Agenda Item 1.6.1 (IMT-2000), Agenda Item 1.9 (Uplinks related to
MSS sharing at 1559-1567 MHz), Agenda Item 1.13.1 (NGSO FSS sharing with
GSO FSS large earth stations) and additional agenda items resulting from
Plenipot Resolutions **87** (Role of the Notifying Administration) and
**86** (Review and Update of the Advance Publication, Coordination and
Notification Procedures).

Enclosed are modifications to your FCC WRC Advisory Committee\'s (WAC)
proposal related to Agenda Item 1.4 (PFD limits 37.5 -- 42.5 GHz). We
support the WAC proposals for Agenda Items 1.5 (HAPS), 1.8 (Earth
stations onboard vessels), and 1.20 (Appendix **S30**) as written.
Additionally, we have noted the WAC proposal for \"No Change\" with
respect to Agenda Item 1.10 (generic MSS/AMS(R)S). In that there is
concern being expressed by the aviation community in all ITU regions,
and the issue has not been clearly resolved, we feel that a proposal is
premature.

\[DRAFT\] PROPOSALS FOR THE WORK OF THE CONFERENCE

Proposals for Agenda Item 1.4

## to consider issues concerning allocations and regulatory aspects related to Resolutions 126 (WRC-97), 128 (WRC-97), 129 (WRC-97), 133 (WRC-97), 134 (WRC-97) and 726 (WRC-97)

# Background

*Requests ITU-R* 1 of Resolution **133 (WRC-97)** requested the ITU-R to
determine whether the power-flux density limits included in Article S21
of the Radio Regulations adequately protect terrestrial services from
FSS networks in the band 37.0-40.0 GHz. Resolution **129 (WRC-97)**
requested the ITU-R to undertake studies of appropriate criteria and
methodologies for sharing, including power flux-density limits, between
the fixed-satellite service and the other services with allocations in
the band 40.5-42.5 GHz.

The results of studies conducted in the ITU-R of known and proposed
non-GSO FSS systems, and of known and proposed [point-to-point
(]{.underline}P-P[)]{.underline} and [point-to-multi-point
(]{.underline}P-MP[)]{.underline} FS systems, indicate that maximum
allowable values of power flux-density of -120/-105 dB(W/m^2^-MHz) at
the surface of the Earth would be adequate to protect systems operating
in the Fixed Service from non-GSO FSS networks in the frequency band
37.5 - 40.5 GHz. These results are applicable for protection of the
Mobile Service in this band as well.

The results of studies conducted in the ITU-R of known and proposed
non-GSO FSS systems, and of known and proposed (P-P) and (P-MP) FS
systems, indicate that maximum allowable values of power flux-density of
‑115/‑105 dB(W/m^2^·MHz) at the surface of the Earth would be adequate
to protect systems operating in the Fixed Service from non-GSO FSS
networks in the frequency band 40.5 ‑ 42.5 GHz. These results are
applicable for the terrestrial Broadcasting Service in this band as
well.

In both cases, the studies were deemed valid for non-GSO FSS systems
comprised of 99 or fewer satellites, and that independent verification
would have to be performed if these levels were to be applied to any
non-GSO FSS system with more than 99 satellites in its constellation.
The results of the studies are reflected in Draft New Recommendation
\[4-9S/AH1\], Maximum Allowable Values of Power Flux-Density at the
Surface of the Earth Produced by Non-Geostationary Satellites in the
Fixed-Satellite Service Operating in the 37.5-40.5 GHz and 40.5-42.5 GHz
Bands to Protect the Fixed Service.

The results of studies conducted in the ITU-R show that, for a range of
non-GSO and GSO fixed-satellite systems, and for a point-to-point and
point-to-multipoint fixed service system operating with elevation angles
that range from 0 - 40^0^, the pfd levels of ‑115/-105 dB(W/m^2^ per
MHz) are adequate to protect the fixed service in the band 37.5-42.5 GHz
from interference caused by GSO fixed-satellite service systems.

On the basis of these conclusions, the United States makes the following
proposals for modifications and additions to Table S21-4 of Article S21
are made, and to suppress Resolutions 133 and 129 (both WRC-97). The
United States bases its proposal to suppress Resolution 133 on the
completion of the power flux-density studies referenced in Resolves 1 of
that Resolution. These power flux density studies were performed
relative to the Fixed Service and are assumed to adequately protect the
co-primary Mobile Service as well. To the extent that there may be
aspects of studies that encompass matters in Resolves 2 of Resolution
133 still ongoing in the ITU-R, particularly on issues of coordination
methodology, the United States may make additional proposals (e.g., for
a new WRC-2000 Resolution) to enable the completion of any such studies
that have not been successfully completed prior to WRC-2000.

**MOD** 10 **S21.16.4** The values given in this table shall not apply
to emissions of space stations on non-geostationary satellites in
networks operating with 100 or more satellites.

**Reasons:** The PFD-review objectives of Resolutions **133 (WRC-97)**
and **129 (WRC-97)** have been met. The values stated above for
non-geostationary satellite orbit FSS systems in the bands 37.5-40.5 GHz
and 40.5-42.5 GHz respectively are included in a draft new
recommendation approved by the ITU-R. See Draft New Recommendation
\[4-9S/AH1\], Maximum Allowable Values of Power Flux-Density at the
Surface of the Earth Produced by Non-Geostationary Satellites in the
Fixed-Satellite Service Operating in the 37.5-40.5 GHz and 40.5-42.5 GHz
Bands to Protect the Fixed Service. The studies under Resolution 129
were done with respect to the Fixed Service but are assumed to be
adequate for protecting the co-primary terrestrial Broadcasting Service
as well. In addition, studies have demonstrated the suitability for
application to geostationary satellite-orbit FSS systems of the current
pfd limits in the 37.5-40 GHz band and the application of the same
limits to the fixed-satellite service in the 40.5-42.5 GHz band.
However, protecting the Radio Astronomy Service to the levels in
existing ITU-R recommendations has proven to be commercially impractical
so that pfd levels for the FSS in the 41.5-42.5 GHz band, an allocation
the U.S. proposes to delete in a separate proposal, would be unnecessary
(see Section 6.1.4.2.3 of the CPM Report).

\[DRAFT\] PROPOSALS FOR THE WORK OF THE CONFERENCE

Proposals for Agenda Item 1.5

to consider regulatory provisions and possible additional frequency
allocations for services using high altitude platform stations, taking
into account the results of ITU-R studies conducted in response to
Resolution **122 (WRC-97)**; (WAC/105(24.06.99))

**Background Information:** Resolution 122 (WRC-97), "Use of the bands
47.2 -- 47.5 GHz and 47.9 -- 48.2 GHz by high altitude platform stations
in the fixed service and by other services", instructs the Director of
the Radiocommunication Bureau, that from 22 November 1997, to accept
notices in the 47.2 -- 47.5 and 47.9 -- 48.2 GHz only for high altitude
platform stations in the fixed service and for feeder links for the
broadcasting-satellite services pending review of sharing studies
between co-primary services in the band. On the basis of studies
conducted in the ITU-R, it is appropriate to modify Resolution **122**
(WRC-97). A draft new Recommendation \[4-9S/AAX\] has been developed
that establishes the performance parameters for FSS antennas that can
share with the HAPS system.

On the basis of these conclusions, the following proposal is made:

**USA/1.5/XX MOD Resolution 122 (WRC-97)**

RESOLUTION 122 (WRC-97)

Use of the bands 47.2-47.5 GHz and 47.9-48.2 GHz by high altitude
platform stations in the fixed service and by other services

The World Radiocommunication Conference (Istanbul, 2000),

considering

a)  that the band 47.2-50.2 GHz is allocated to the fixed, mobile and
    fixed-satellite services on a co-primary basis;

*b)* that WRC-97 made provision for operation of high altitude platform
stations, also known as stratospheric repeaters, within the fixed
service in the bands 47.2-47.5 GHz and 47.9-48.2 GHz;

*c)* that ITU has among its purposes "to promote the extension of the
benefit of the new telecommunication technologies to all the world's
inhabitants" (No. 6 of the Constitution of the ITU (Geneva, 1992));

*d)* that systems based on new technologies using high altitude
platforms in the bands 47.2-47.5 and 47.9-48.2 GHz will be able to
provide high-capacity, competitive services to urban and rural areas;

*e)* that high altitude platform systems are in an advanced stage of
development and some countries have notified such systems to ITU;

*f)* that WRC-97 adopted a new definition of high altitude platform
stations in Article **S1**, modified No. **S11.24** and added No.
**S11.26** in the Radio Regulations providing for notices relating to
assignments for high altitude platform stations in the bands 47.2-47.5
GHz and 47.9-48.2 GHz;

*g)* that the ITU-R has confirmed that sharing is feasible between high
altitude platform stations and the FSS;

*h)* that technical studies are still required in order to ascertain the
extent to which sharing of the bands 47.2-47.5 GHz and 47.9-48.2 GHz is
feasible between systems using high altitude platforms in the fixed
service and systems in the fixed and mobile services, and to ascertain
the requirements to protect radio astronomy services in adjacent bands
from spurious emissions;

*i)* that the radio astronomy service has primary allocations in the
bands 42.5-43.5 GHz and 48.94-49.04 GHz;

resolves

1 to urge administrations to facilitate coordination between high
altitude platform stations in the fixed service operating in the bands
47.2-47.5 GHz and 47.9-48.2 GHz and other co-primary services in their
territory and adjacent territories;

2 that, on a provisional basis, the procedures of Article **S9** shall
be used for coordination between satellite systems and high altitude
platform systems;

3 to request ITU-R to carry out urgently studies on the appropriate
technical sharing criteria for the situations referred to in
*considering* *h)*, with priority given to the sharing with other
systems in the fixed service

4 that WRC-03 should review the results of these studies and consider
refinement of the regulatory provisions for high altitude platform
technologies,

instructs the Director of the Radiocommunication Bureau

1 that notices concerning high altitude platform stations that were
received by the Bureau prior to 22 November 1997, and provisionally
recorded in the Master International Frequency Register in accordance
with the provisional rule of procedure issued by the Board, shall be
maintained;

2 that pending review of the sharing studies in *considering* *h)* , the
Bureau shall accept notices in the bands 47.2-47.5 GHz and 47.9-48.2 GHz
only for high altitude platform stations in the fixed service and for
the fixed-satellite service, including feeder links for the
broadcasting-satellite service. Proposal for Agenda Item 1.6.1

(review of spectrum and regulatory issues for advanced mobile
application in the context of IMT-2000, noting that there is an urgent
need to provide more spectrum for the terrestrial component of such
applications and that priority should be given to terrestrial mobile
spectrum needs, and adjustments to the table of frequency allocations as
necessary)

**Background Information:** The United States proposes [NOC]{.underline}
for the bands 2 700-2 900 MHz and 2 900- 3 100 MHz. These two bands are
used extensively throughout the world for the meteorological radars and
other radionavigation and radiolocation systems. The impact of an
allocation for mobile service use by IMT-2000, on these critical radar
operations has not been studied by the ITU-R.

The 2700-2900 MHz band is used for aeronautical radionavigation radars
providing essential safety-of-life related terminal approach guidance
for commercial aircraft. The band 2900-3100 MHz is used extensively by
radars and radar beacons operating in the maritime radionavigation
service, including vessel traffic services, harbor - harbor entrance
navigation and collision avoidance. Marine radars using this band
provide an essential navigation capability in poor weather; for example,
providing a factor of ten improvement in radar target detection during a
snowstorm to that of shipborne radars operating in the 3cm band. The
NEXRAD weather radar system, operating at 2900-3100 MHz, also provides
weather location and prediction information critical for public safety.
Studies made during the implementation of NEXRAD has shown that air
traffic control and weather radar cannot operate in the same band and in
the same vicinity of marine radars and racons without causing
interference.

Working Party 8B, in a liaison statement to Task Group 8/1, expressed
serious concerns that TG8/1 was recommending critical radionavigation,
radiolocation, meteorological aids and telemetry bands via CPM text to
WRC-2000 for possible reallocation to the Mobile Service exclusively
without consulting the responsible working party.

The CPM text concludes that, given the technical characteristics of the
radionavigation, radiolocation and meteorological radars, (e.i.r.p. in
the order of 1 GW in some systems and the trend towards high duty
cycles), and the need to operate in accordance with the protection
criteria contained in ITU-R recommendations, sharing with IMT-2000
systems is considered to be feasible only when explicitly confirmed by
ITU-R sharing studies.

# Proposal for Agenda Item 1.8

(to consider regulatory and technical provisions to enable earth
stations located on board vessels to operate in the fixed-satellite
service (FSS) networks in the bands 3 700 - 4 200 MHz and 5 925 -
6 425 MHz, including their coordination with other services allocated in
these bands)

**Background Information:** This item concerns provision of
communications by earth stations on board vessels using frequencies
allocated to the fixed-satellite service and used by existing space
segment in the fixed-satellite service. These stations operate in three
distinct modes: at sea; while stationary in or near port; and in motion
approaching or departing from port.

Operations at sea (beyond a certain distance for near-shore
coordination) by earth stations on board vessels in the fixed-satellite
service do not present a potential for interference to stations in the
fixed service operating in accordance with the 6 GHz FS allocation, and
therefore need not be coordinated. Operations while these earth stations
are stationary at pre-determined points can be coordinated bilaterally
with fixed service systems. Technical and regulatory issues concern the
potential for interference between in-motion operations by these ESV
earth stations operating close to shore and stations in the fixed
service both on and offshore.

Attached is regulatory text that provides the framework for the
authorization of earth stations on board vessels in the three different
situations of operation; and through the application of constraints
provides for the continued growth of terrestrial fixed services
operating in accordance with the Radio Regulations.

There are a number of references to the distance \[XXX\] in the
following proposal for Agenda Item 1.8. Determination of the \[XXX\]
value or values must be accomplished before any regulatory/procedural
proposals could be implemented.

**Proposal:**

##### ADD

Resolution ZZZ (WRC-2000)

Provisions to Enable Earth Stations Located on board Vessels to Operate
in Fixed-Satellite Service Networks in the Bands 3 700-4 200 MHz and
5 925-6 425 MHz

The World Radiocommunication Conference (Istanbul, 2000),

considering

a)  that the technology exists that would permit the use of FSS networks
    by earth stations on board vessels (ESV) in the bands 3 700-4
    200 MHz (space-to-Earth) and 5925-6425 MHz (Earth-to-space);

b)  that ESVs have the potential to cause unacceptable interference to
    fixed service systems in the band 5 925-6 425 MHz;

c)  that some administrations have been operating ESVs for several years
    under Radio Regulation S4.4;

d)  that ESV operations require considerably less than the full
    bandwidth in this FSS allocation and only a portion of the visible
    geostationary arc;

e)  that in order to ensure the protection and future growth of the FS,
    the ESV must operate with certain operational constraints;

f)  that the territory of an administration includes any off-shore
    structures or platforms with stations authorized by that
    administration;

g)  that a minimum distance from the territory of an administration can
    be calculated beyond which the ESV will not cause unacceptable
    interference to the fixed service in this band.

resolves

1.  that an earth station on board a vessel (ESV) may be considered a
    station in the fixed-satellite service while receiving in the 3
    700 - 4 200 MHz band and transmitting in the 5 925 - 6 425 MHz band;

2.  that operation of ESVs that are at least \[XXX\] km from the
    territory of an administration in which stations in the fixed
    service operating in accordance with the Radio Regulations require
    no coordination or agreement;

3.  that an ESV may be operated, either at a stationary position or
    while in motion, within \[XXX\] km from the territory of an
    administration with any fixed service station operating in
    accordance with the Radio Regulations using the bands
    3 700 - 4 200 MHz (space-to-Earth) and 5 925 - 6 425
    (Earth-to-space) of the fixed-satellite service, subject to the
    following:

```{=html}
<!-- -->
```
(a) the authority for operating on radio frequencies within \[XXX\] km
    of territory on which such stations in the fixed service are
    operating belongs with the Administration responsible for that
    territory; however, the responsibility for the ESV lies with the
    Administration that authorized the use of the ESV,

(b) The administration that authorizes the use of the ESV in these bands
    shall ensure that such stations do not cause unacceptable
    interference to stations in the fixed service which themselves are
    established and operated in accordance with the Radio Regulations;

(c) Before ESVs operate in the fixed-satellite service in these bands:

```{=html}
<!-- -->
```
(i) a set of frequencies will be established in each area of intended
    operation for such use that have been coordinated with all other
    potentially affected users;

(ii) this set of frequencies will include only the necessary spectrum
     per vessel in these bands (maximum necessary bandwidth per ESV is
     2.346 MHz);

(iii) coordination will be accomplished between the Administration(s)
      with authority over the potentially affected fixed service
      stations operating in these bands and the Administration that
      authorizes the ESV to operate while stationary in these bands; in
      accordance with the S9.17 provisions of the Radio Regulations;

(iv) upon completion of such coordination, the ESV will be authorized to
     operate in the fixed-satellite service subject to appropriate
     operational constraints in these bands;

```{=html}
<!-- -->
```
(a) a list of the ESVs authorized to operate within \[XXX\] km of
    territory on which stations in the fixed service are operating in
    accordance with the Radio Regulations, the frequencies used and
    associated operational conditions that have been coordinated shall
    be established and maintained by the Administration responsible for
    the territory in which the fixed service stations are located; such
    list shall include a point of contact for obtaining this
    information;

(b) ESV operators must comply with the conditions established by the
    authorizing Administration(s); ESV use will be limited to the areas
    specified in the authorization with all of the constraints including
    minimum speeds.

```{=html}
<!-- -->
```
1.  that coordination of in-motion ESVs within \[XXX\] km of all
    stations in the fixed service operating in accordance with the Radio
    Regulations shall be accomplished using the provisions of the Annex
    to this Resolution.

2.  that every ESV operating under this provision shall be equipped with
    an automatic mechanism for continuously determining the location of
    the vessel and disabling operations in the event the vessel is
    within \[XXX\] km of the territory of an administration with
    stations in the fixed service operating in accordance with the Radio
    Regulations or that the ESV is outside any geographic area where its
    operation has been coordinated. The ESV shall also incorporate an
    automatic mechanism to terminate transmissions (a) when the antenna
    subsystem loses lock on the satellite and/or the ability to maintain
    tracking accuracy; or (b) when the antenna elevation drops below the
    ten degree required minimum elevation angle or (c) or when any
    operating parameter fails to meet the constraints established in the
    terms of the coordination agreement.

3.  that Administrations that authorize the use of the ESV shall ensure
    that personnel of vessels with ESVs are adequately qualified and
    certificated in accordance with the requirements of those
    Administrations to ensure the proper operation of the ESVs in
    accordance with the provisions of this Resolution.

4.  that the operator of the ESV shall, as appropriate, provide evidence
    of the basis for the authority under which the station is operating
    (e.g. license or certification). When such authority cannot be
    produced or when manifest irregularities are observed,
    Administrations in whose territory vessels equipped with ESVs are
    visiting may inspect the ESV installations in order to satisfy
    themselves that the ESVs conform to the conditions imposed by this
    resolution, including the capability indicated in section 5.

5.  that Administrations which authorize the use of the ESV shall ensure
    that the ESV shall be capable of operating in compliance with the
    requirements of this Resolution.

Annex

**USE OF ESVS WHILE IN MOTION WITHIN THE**

DISTANCE \[XXX\] km IN THE BANDS 3700-4200 MHz AND

**5925-6425 MHz**

1.  Unless otherwise provided in a bilateral coordination agreement, the
    minimum constraints on ESVs shall include:

```{=html}
<!-- -->
```
a.  minimum diameter of the ESV antenna must be at least 2.4 m;

b.  minimum antenna elevation angle must be at least 10 degrees;

c.  maximum necessary bandwidth/vessel: 2.346 MHz;

d.  maximum necessary bandwidth in a single operating area: 36 MHz;

e.  maximum ESV transmitter power spectral density 17 dB(W/MHz) (at
    input to the antenna);

f.  minimum satellite tracking accuracy of 0.2 degrees;

g.  maximum half-power antenna beamwidth of 1.5 degrees

```{=html}
<!-- -->
```
1.  The ESV transmissions from vessels within \[XXX\] km of stations in
    the fixed service operating in accordance with the Radio Regulations
    shall be based on agreements between the administrations concerned.

2.  In order not to inhibit the growth of the fixed service,
    authorizations and agreements for the use of these frequencies by
    ESVs in accordance with the conditions of the coordinations shall
    extend for a fixed period of time (e.g. 1-3 years), but may be
    renewed;

3.  ESVs will not claim protection while in motion from fixed service
    station transmissions.

4.  Methods for establishing the basis for ESV use of frequencies in
    this band should be based on the most recent Recommendations of the
    ITU-R applicable to sharing between the fixed service and ESV use of
    the band.

**(Draft) Proposals for the Work of the Conference**

## Proposals for Agenda Item 1.9

To Take Into Account the Results of ITU-R Studies in Evaluating the
Feasibility of an Allocation in the Space-to-Earth Direction to the
Mobile-Satellite Service (MSS) in a Portion of the 1 559 - 1 567 MHz
Frequency Range, in Response to Resolutions **213 (WRC-97)** and **220
(WRC-97)**;

**Background Information**: Under the general examination of spectrum
for the Mobile-Satellite Service in the 1 to 3 GHz frequency range, it
is appropriate to review the situation with some of the existing MSS
allocations that have not been brought into use. Allocations to the
mobile satellite services in the band 1 492 - 1 525 and 1 675 - 1 710
MHz bands were made at WARC-92 for Region 2. Since that time it has been
found that it is not possible to implement MSS in these bands because of
their use by terrestrial, meteorological, and meteorological satellite
services. This has been documented in studies undertaken by the ITU-R
for WRC-95, WRC-97 and, specifically for the 1 675 - 1 710 MHz band, in
the CPM-2000 report. It has been shown conclusively as a result of
studies called for by Resolution **213** that these mobile-satellite
service allocations are not able to be used, therefore they should be
removed from the Table of Allocations.

**Proposal:**

**DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE**

**Proposal for Agenda Item 1.13.1**[^1]

**1.13:** on the basis of results of the studies in accordance with
Resolutions 130(WRC-97), 131(WRC-97), and 538(WRC-97):

> **1.13.1:** *to review and, if appropriate, revise the power limits
> appearing in Articles **S21** and **S22** in relation to the sharing
> conditions among non-GSO FSS, GSO FSS, GSO broadcasting-satellite
> service (BSS), space sciences and terrestrial services, to ensure the
> feasibility of these power limits and that these limits do not impose
> undue constraints on the development of these systems and services;*
>
> **1.13.2:** *to consider the inclusion in other frequency bands of
> similar limits in Articles **S21** and **S22**, or other regulatory
> approaches to be applied in relation to sharing situations;*

**Background Information:** WRC-97 adopted provisional power flux
density limits in certain frequency bands which would apply to non-GSO
FSS systems to protect GSO FSS networks, and GSO BSS networks.
Resolution 130 (WRC-97), *Use of Non-Geostationary Systems in the
Fixed-Satellite Service in Certain Frequency Bands*, and Article **S22**
of the Radio Regulations contain limits corresponding to an interference
level caused by one non-GSO system in the frequency bands 10.7-12.75
GHz, 17.8-18.6 GHz, and 19.7-20.2 GHz. Studies demonstrate that neither
the WRC-97 provisional EPFD~down~ limits and associated percentages of
time nor the proposed modifications agreed during ITU-R studies
adequately protect existing GSO FSS networks with very large earth
station antennas. Section 3.1.2 of the draft CPM report for WRC-2000
concludes that transmissions to earth stations with very large antennas
need to be protected and that an additional regulatory procedure would
be necessary. Coordination triggers and example regulatory and
procedural text were also agreed. Building on the draft CPM report text,
this proposal includes additions and/or modifications to Articles **S9**
and **S22** and Appendices **S4** and **S5** to require coordination
between non-GSO FSS transmitting space stations and GSO receive earth
stations with very large earth station antennas.

|            | **Reasons:** GSO FSS earth stations with very large     |
|            | antennas are not adequately protected by the EPFD~down~ |
|            | limits contained in Table **MOD** **S22-1** and         |
|            | case-by-case coordination of systems operating          |
|            | co-frequency, co-directional links in the               |
|            | space-to-Earth direction is needed. The proposed **ADD  |
|            | S9.7A** and **ADD** **S9.7B** would require             |
|            | coordination between non-GSO FSS transmit satellites    |
|            | and GSO FSS receive earth stations with very large      |
|            | antennas. By referring to coordination provisions under |
|            | **S9.7A** and **S9.7B**, the request for coordination   |
|            | would be sent by the requesting administration to the   |
|            | Bureau under **S9.30**. The Bureau would act under      |
|            | **S9.34** to identify administrations with which        |
|            | coordination may need to be effected and publish the    |
|            | information in the Weekly Circular. Since coordination  |
|            | between administrations operating non-geostationary     |
|            | (non-GSO) satellite systems in the fixed-satellite      |
|            | service (FSS) and administrations operating GSO FSS     |
|            | space networks with specific very large earth station   |
|            | antennas is a new type of coordination that does not    |
|            | currently exist in Article **S9**, it is necessary to   |
|            | add two new entry points in Article **S9:**             |
|            |                                                         |
|            | • One entry point to enable the administration          |
|            | operating the non-GSO satellite space stations to       |
|            | request coordination with administrations operating GSO |
|            | FSS space networks with specific very large earth       |
|            | station antennas.                                       |
|            |                                                         |
|            | • Another entry point to enable the reciprocal          |
|            | coordination to take place, i.e. the possibility for an |
|            | administration operating a GSO FSS space network with   |
|            | specific very large earth station antenna to request    |
|            | coordination with administrations having non-GSO FSS    |
|            | transmit space stations.                                |

**Reasons:** This is consequential to **ADD** **S9.7A** and **ADD
S9.7B**. Administrations will need to submit specific information for
earth stations associated with geostationary-satellite networks in the
fixed-satellite service meeting the conditions in the proposed addition
to Appendix **S5**. Since there is no requirement to give the specific
locations of earth stations today, there may need to be a resolution
written to have typical earth stations associated with GSO FSS networks,
already in coordination or notified, that meet the criteria to be
brought in as specific earth stations. In this resolution, there will
have to be some guidance on priorities. In keeping with ITU principles
concerning coordination of satellite networks operating in the same
direction, the coordination will be between the administrations
responsible for the satellite networks. Modifications in column two for
\"Notification or coordination of a GSO network (including Appendix
**S30B**)\" will be required. Additional guidance will need to be added
to the *Instructions for Filling Out the Form of Notice ApS4/II and
ApS4/III Relating to Space Radiocommunication Stations* distributed by
CR/65.

\[DRAFT\] PROPOSALS FOR THE WORK OF THE CONFERENCE

Proposals for Agenda Item 1.20

## to consider the issues related to the application of Nos. S9.8, S9.9 and S9.17 and the corresponding parts of Appendix S5 with respect to Appendices S30 and S30A, with a view to possible deletion of Articles 6 and 7 of Appendices S30 and S30A, also taking into consideration Recommendation 35 (WRC-95);(WAC085)

**Background Information:** Annex 1 to Appendix **S30** of the Radio
Regulations specifies limits for determining whether a service is
affected by a proposed modification to the BSS Plan or when it is
necessary to seek the agreement of any other administration. Section 5
of Annex 1 specifies limits to the change in the PFD to protect the
terrestrial services of administrations in Regions 1 and 3 from
modifications to the Region 2 Plan.

Section 5c specifies the PFD limits for administrations in Region 1 east
of longitude 30°E. This PFD limit is very tight at low angles of
elevation. In order to meet this PFD limit the Region 2 BSS spacecraft
EIRP towards Alaska must be significantly lower compared to the
continental United States. As a result the provision of BSS service to
Alaska, from U.S. orbital assignments at 101W, 110W and 119W, requires
larger BSS receive dishes, in some cases as large as 1.8 m. This will
also be the case for Region 2 administrations that propose to modify
their assignments to provide service to the United States. The U.S.
Administration requires provision of service to Alaska when technically
feasible.

A relaxation in the PFD limit in Section 5c of Annex 1 of Appendix
**S30**, as proposed below, would allow the use of 60 cm BSS receive
dishes in Alaska for BSS service from the 101W, 110W and 119W orbital
locations.

It is noted that a Joint Rapporteur Group between JWP 10/11S and WP 9D
has been established to evaluate the power flux density limits specified
in Section 5c and perhaps other terrestrial power flux density limits in
Annex 1 of Appendix **S30**.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE

ROLE OF THE NOTIFYING ADMINISTRATION WHEN ACTING AS THE NOTIFYING
ADMINISTRATION ON BEHALF OF A NAMED GROUP OF ADMINISTRATIONS

Resolution 87 (Minneapolis, 1998)

The Administration of the United States, in particular as the notifying
administration for INTELSAT, has considered any possible modifications
to the Radio Regulations under Resolution 87. This Administration has
not experienced any difficulties either with other administrations
acting as the notifying administration for a group of named
administrations or acting as the notifying administration for INTELSAT.
The Administration of the United States believes that the Radio
Regulations are now adequate in this area and require no changes
regarding the responsibilities of the notifying administration. The
notifying administration and the intergovernmental organizations should
retain the flexibility of making their own arrangements for interfaces
with the ITU. Members of an intergovernmental organization responsible
for satellite networks can best determine how it needs to comply with
the Radio Regulations.

DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE

Review and Update of the Advance Publication, Coordination and
Notification Procedures

##### Resolution 86 (Minneapolis, 1998)

##### Background

1.  Resolution **86** (Minneapolis, 1998) resolves to request WRC-2000
    and subsequent WRCs to continually review and update the advance
    publication, coordination and notification procedures, including the
    associated technical characteristics, and the related Appendices of
    the Radio Regulations, so as to ensure that they reflect the latest
    technologies, as well as to achieve additional simplification and
    cost savings for the Radiocommunication Bureau and administrations.

##### Discussion

2.  One enabler facilitating coordination and associated resolution of
    difficulties is timely availability of information to all parties
    concerned. For this reason, the Radio Regulations have contained a
    provision (currently No. **S9.38**) calling for the publication of
    complete coordination information in the Weekly Circular within four
    months of receipt by the BR. Unfortunately, that timely publication
    has not been possible; currently, the publication backlog is on the
    order of twenty months.

3.  While we are hopeful that incentives will emerge from review of the
    process by administrations to promote improvements in the satellite
    procedures, it seems doubtful that substantial reductions in the
    backlog and processing delays will be realized without fundamental
    process changes that must be established in the Radio Regulations by
    WRCs.

4.  One such change centers on the idea that complete examination (by
    the BR) of coordination requests might occur in parallel with the
    review undertaken by administrations. This would reduce the actions
    to be undertaken by the BR *before* it initially publishes a
    coordination request, and should make the information available to
    administrations much earlier. This can be the starting point for a
    series of changes to Article **S9**. It is desired to make the
    process practical for the BR and meaningful to administrations. The
    fundamental responsibility of the BR to examine and publish
    coordination requests is retained, with some revision of the
    associated time frames.

5.  Examples of a two-step coordination publication procedure are given.
    For the first coordination publication, there would be minimal
    examination by the Radiocommunication Bureau (completeness of data,
    conformity with the Table of Allocations and conformity with the
    bringing into use provisions of the Radio Regulations). The second
    publication would present the results of the Bureau's technical and
    coordination examinations that may be subject to a further comment
    if additional administrations are identified as affected or if
    technical information in the first publication needed modification
    to be in compliance with the Regulations.
