ELEMENTS 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 ...
Plan & List Beams
WRC-2000 PLAN
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 3 LISTS
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 LISTS
• 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 LISTS (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 noninterference basis in case of disagreements
• Provision to accommodate assignments for
new ITU Member States
COMPATIBILITY BETWEEN
PLAN 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 for
Regions 1 & 3 Plan Assignments
Equivalent Protection Margin (EPM) is used as
compatibility criteria for the Regions 1 & 3 Plans as
follows:
 3
(  M i / 10) 
EPM  10 log  10

 i 1

C
Mi = protection margin =
I iaggr
 PRi
(dB)
i = interference type (1=co-channel, 2 & 3 = upper &
lower first adjacent channels);
PRi = protection ratio for a given interference type i.
Compatibility Criteria for
Region 2 Plan Assignments
Overall Equivalent Protection Margin (OEPM) is used as
compatibility criteria for the Region 2 Plan as follows:
 5
(  M i / 10) 
OEPM  10 log  10

 i 1

Mi = protection margin =
C
I iaggr
 PRi
(dB)
i = interference type (1=co-channel, 2&3=upper &
lower first adjacent channels, 4&5= upper & lower
second adjacent channels);
PRi = protection ratio for a given interference type i.
Compatibility Criteria for
Regions 1 & 3 List Assignments
• 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
MAIN REGULATORY ASPECTS
• BSS Downlink/ Feeder-link
- Modification/Addition/Coordination (Article 4)
- Notification/Implementation (Article 5)
• Terrestrial
- Coordination/Notification (Article 6)
• FSS

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)
ARTICLE 4 EXAMINATION

• 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
ARTICLE 4 EXAMINATION

• 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 feederlink space stations (17.8-18.1 GHz)
- GIBC(Appendix 8): delta T/T
Processing of Article 4
Submissions (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
Submissions (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 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 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.
