ELEMENTS OF PLANSELEMENTS OF PLANS

National assignments are included in:• Articles 10 & 11 of Ap.30 (downlink)• Articles 9 & 9A of Ap.30A (feeder-link)

These Articles describe:orbital position, channels, polarisation, power levels, antenna patterns, emission designation, beam coverage, grouping ...

PPlan & List Beamslan & List Beams

WRC-2000 PWRC-2000 PLANLAN WRC-2000 developed a new Plan that included:• 10 channels in Region 1 and 12 channels in Region 3;• new national beams/assignments for East Timor and the

Seychelles;• 5 extended-coverage national beams for 15

administrations;• 30 "composite" beams;• new protection ratios and other technical parameters;• orbital position preferences for 63 administrations; and• 20 other national preferences.

REGIONS 1 AND 3REGIONS 1 AND 3 L LISTISTSS

Regions 1 and 3 Lists of Additional Uses:

• Downlink List- 12 GHz List (currently 32 networks/3329 assignments)

• Feeder-link List- 14 GHz List (currently 1 network/6 assignments) - 17 GHz List (currently 34 networks/2064 assignments)

ELEMENTS OF LISTELEMENTS OF LISTSS

• Created at WRC-2000.• Separated from the Plans and annexed

to the Master Register (MIFR).• Lists are evolving and will be updated

and published periodically by the BR.• Assignments in the Lists must be

compatible with the Plans and other services.

ELEMENTS OF LISTELEMENTS OF LISTSS (cont’d) (cont’d)

• Digital modulation only• Data elements submitted using Appendix 4• Non-monopolisation provisions• 15 year time limit • Provisions for use of assignments on a non-

interference basis in case of disagreements• Provision to accommodate assignments for

new ITU Member States

COMPATIBILITY BETWEEN COMPATIBILITY BETWEEN PLAN AND LIST ASSIGNMENTSPLAN AND LIST ASSIGNMENTS

• Plan assignments– Regions 1 & 3 Plan based on EPM– Region 2 Plan based on OEPM

• List assignments– Regions 1 & 3 List based on EPM and also

PFD for the downlink.

Compatibility Criteria forCompatibility Criteria forRegions 1 & 3 Plan AssignmentsRegions 1 & 3 Plan Assignments

Equivalent Protection Margin (EPM) is used as compatibility criteria for the Regions 1 & 3 Plans as follows:

Mi = protection margin = (dB)

i = interference type (1=co-channel, 2 & 3 = upper & lower first adjacent channels);

PRi = protection ratio for a given interference type i.

Overall Equivalent Protection Margin (OEPM) is used as compatibility criteria for the Region 2 Plan as follows:

i = interference type (1=co-channel, 2&3=upper & lower first adjacent channels, 4&5= upper & lower second adjacent channels);

• Based on both EPM and PFD criteria.– EPM criteria as per the Regions 1 & 3 Plan– PFD criteria also used to identify affected

assignments as per Annex 1 of Ap.30

MAINMAIN REGULATORY REGULATORY ASPECTS ASPECTS

• BSS Downlink/ Feeder-link- Modification/Addition/Coordination (Article 4) - Notification/Implementation (Article 5)

• Terrestrial - Coordination/Notification (Article 6)

• FSS - Coordination/Notification (Article 7)

• Space Operation/TT&C in the Guardbands - Coordination/Notification (Article 2A)

AARTICLERTICLE 5 5 EXAMINATION EXAMINATION

• conformity with the Convention, Table of Allocations, other provisions

• conformity with the Plan and List (except reduced e.i.r.p, reduced coverage etc.)

• protection of other services in specific cases• Notified technical characteristics have to be

the same as those in the Plans or Lists except those allowed in provision 5.2.1 d)

AARTICLERTICLE 4 4 EXAMINATION EXAMINATION (Appendix (Appendix 3030 Regions Regions 1 1 && 3)3)

• Protection of the Regions 1 & 3 Plan and List - SPS/MSPACE: EPM & PFD calculations

• Protection of Region 2 Plan - GIBC(PXT)/GIMS: PFD

• Protection of Terrestrial Services - GIBC/GIMS: PFD

• Protection of Region 2 and Region 3 FSS - GIBC(PXT)/GIMS: PFD

AARTICLERTICLE 4 EXAMINATION 4 EXAMINATION (Appendix (Appendix 3030A Regions 1&3)A Regions 1&3)

• Protection of Regions 1&3 Plan and Lists - SPS/MSPACE: EPM calculation

• Protection of the Region 2 Plan - GIBC(Appendix 8): delta T/T

• Protection of Region 2 FSS receiving feeder-link space stations (17.8-18.1 GHz) - GIBC(Appendix 8): delta T/T

Processing of Article 4 Processing of Article 4 Submissions Submissions (1)(1)

• Bureau is currently processing all as yet unpublished submissions received under Article 4 using the revised Appendices 30 and 30A in accordance with Resolution 546 (WRC-03).

• Special Sections, that contain the filed satellite network characteristics and potentially affected administrations, are being published in BR IFICs.

• Administrations should examine each BR IFIC to see if it’s assignments are affected and respond within 4 months.

Processing of Article 4 Processing of Article 4 Submissions Submissions (2)(2)

• Affected administrations that do not comment within the 4 month period are deemed to have agreed.

• After the 4 month period has expired, the BR prepares a list of coordination agreements required and publishes this in a Part D Special Section.

• Results of the Bureau’s MSPACEg calculations are also placed on the BR IFIC.

• Workshop session will explain this in more detail.

Plan and List dataPlan and List data• All Plan and List assignment data can be found on

the BR IFIC & the ITU website at:

http://www.itu.int/ITU-R/space/plans/index.html

• Contained in the SPS database (SNS Version 5 format).

• Contains the technical characteristics and reference situation for all Plan, List and pending Article 4 assignments.

• The SPS database is evolving and is updated regularly.

Post WRC-03 ActivitiesPost WRC-03 Activities

• Update of the Reference Situation (EPM/OEPM) for Plan & List assignments;

• Implementation of Resolution 548 (WRC-03);• Implementation of the grouping concept in

Regions 1 & 3; • Processing of Article 2A, 4 & 5 notices;• Implementation of Resolution 547.
