APPENDIX 30B FSS PLAN

• Adopted by the World Administrative Radio
  Conference on the Use of the Geostationary-Satelli
  te Orbit and the Planning of Space Services
  Utilizing It (WARC ORB-88).
• The objective of the Appendix 30B Plan is to
  guarantee in practice, for all countries,
  equitable access to the geostationary-satellite
  orbit in the frequency bands of the
  fixed-satellite service covered by that Appendix.

7
TYPES OF SYSTEMS

• The FSS Plan contains two parts
• PART A
• National Allotments
• PART B
• Existing Systems
• Two other types of systems can be included in the
  List
• Subregional Systems
• Additional Uses

8
LIST OF ASSIGNMENTS

• Assignments derived from allotments in Part A
• Assignments relating to existing systems in Part
  B
• Assignments relating to subregional systems
• Assignments relating to additional uses

9
MAIN REGULATORY ASPECTS
10
ELEMENT OF ALLOTMENT (1)

• Nominal orbital position
• Bandwidth of 800MHz (uplink and downlink)
• Service area for national coverage
• Generalized parameters
• Predetermined arc (PDA)

11
ELEMENT OF ALLOTMENT (2)

• General Basic technical characteristics
• Annex 1 of Appendix 30B
• Type of modulation (any type), Polarization
  (any), C/N, Protection ratio, System noise,
  Antenna, reference bandwidth, pointing accuracy
  etc.
• Most of them are characteristics used for
  establishing the Plan ? can be different for
  modifications
• However, when shall is used ? has to be
  observed

12
ELEMENT OF ALLOTMENT (3)

• National allotments are included in
• Article 10 of AP30B (Part A of the Plan)
• This Article describes
• orbital position, power levels, PDA, service arc
  and ellipse parameters ...
• More details like the test points associated
  to each beam are included in the electronic files
  of AP30B which can be found in the ITU WEB site
  http//www.itu.int/itu-r/space/plans/AP30B

13
EXISTING SYSTEM

• Recorded in the MIFR before the adoption of the
  Plan, or
• Coordination procedure has been initiated before
  the adoption of the Plan, or
• Advance publication information was received by
  the BR before 8 August 1985
• Included in Article 10 of AP30B (Part B of the
  Plan)

14
SUBREGIONAL SYSTEM

• Satellite system created by agreement among
  neighbouring countries
• Intended to provide domestic or subregional
  services within the geographical areas of the
  countries concerned

15
ADDITIONAL USE

• Allowed in case of a requirement whose
  characteristics differ from those used in Part A
  of the Plan
• Such requirement can be met only if
• the administration has already converted all or
  part of its allotment into an assignment, or
• the requirement cannot be met by the conversion
  of the allotment into an assignment

16
COMPATIBILITY CRITERIA (1)

• Compatibility with Plan and List
• Aggregate C/I ratio of 23 dB (26 dB for
  submissions received before 5 July 2003)
• Degradation tolerance is less than 0.05dB
• Single entry C/I ratio of 27 dB (30 dB for
  submissions received before 5 July 2003)
• Degradation tolerance is less than 0.05dB

17
COMPATIBILITY CRITERIA (2)

• These criteria may be changed later on due to the
  implementation of systems. For instance, in a
  coordination process an administration can agree
  with lower levels of aggregate and/or
  single-entry C/I
• The single entry C/I criterion will be more
  stringent in case of implementing a system which
  is not complying with the Macrosegmentation
  Concept

18
COMPATIBILITY CRITERIA (3)

• Compatibility with terrestrial services
• PFD hard limit (Art. 21 of RR)
• Coordination contour (Art. 9, 11 of RR AP7)

19
PREDETERMINED ARC (PDA) (1)

• The PDA is a segment of the GSO about a nominal
  orbital position, associated to each satellite
  system
• The width of the PDA is reduced as the stage of
  development of the system progresses
• 10 degree Pre-design stage
• 5 degree Design stage
• 0 degree Operational Stage

20
PREDETERMINED ARC (PDA) (2)

• Pre-design stage
• Part A allotments
• Design stage
• assignments related to allotments or subregional
  systems for which the Bureau has received
  complete information for implementation and
  existing systems with complete API
• Operational stage
• assignments related to additional uses for which
  the Bureau has received complete information for
  implementation or complete notified assignments
  as well as existing systems with complete request
  for coordination or notification

21
PREDETERMINED ARC (PDA) (3)

• An administration is not considered as affected
  if its nominal orbital position is moved within
  the corresponding PDA while keeping interference
  within the accepted levels
• In other words, nominal orbital position can be
  moved by other administrations
• Sequential treatment of the submissions (RoP
  6.12)

22
PREDETERMINED ARC (PDA) (4)

• The PDA concept may be applied only
• To provide an allotment to a new Member State
• When converting an allotment into an assignment
• To accommodate a subregional system
• To resolve incompatibilities with existing
  systems (except for the implementation of
  additional uses)
• To resolve incompatibilities with assignments in
  the List (except for the implementation of
  additional uses)

23
GENERALIZED PARAMETERS (1)

• A C
• Up Down link interference-producing capability
  expressed by the respective off-axis e.i.r.p.
  density
• B D
• Up Down link interference sensitivity expressed
  by the respective off-axis receiver sensitivity
  to interfering e.i.r.p. density

24
GENERALIZED PARAMETERS (2)

• If the calculated A, B, C D values are less
  than or equal to those in the Plan, the
  implementation of the allotment is in conformity
  with the Plan
• Allotments can also be implemented with A or C
  values greater than that in the Plan to the
  extent that compatibility with other systems is
  achieved
• Allotments can also be implemented with higher
  values of B or D, which implies acceptance of
  higher values of interference

25
IMPLEMENTATION OF ALLOTMENTS Sections I and IA
of Article 6 (1)

• Implementation of allotments of Part A, i.e.
  conversion of allotments into assignments, is
  straightforward if
• They have the same or better characteristics than
  those in the Plan (conformity with Part A)
• They comply with the macro segmentation concept
• They are compatible with Part B

26
IMPLEMENTATION OF ALLOTMENTS Sections I and IA
of Article 6 (2)

• The macro segmentation concept was introduced as
  a means to avoid coordination during the
  implementation of an allotment
• When the macro segmentation scheme is not
  observed, the allotment can be implemented if
  compatibility with other systems is achieved
• The upper 60 of each allotment band should be
  used for high-density carriers and the lower 40
  for low-density carriers. The high density
  carriers are those whose ratio of power spectral
  density peak (4 kHz) to average (necessary
  bandwidth) is greater than 5 dB. The low density
  carriers are those for which this ratio is less
  than 5 dB.
• Applicable also sub-regional systems and
  additional uses (RoP)

27
IMPLEMENTATION OF ALLOTMENTSSections I and IA of
Article 6 (3)

• The conditions for conformity with Part A are
• The service area is not greater than that in Part
  A
• The calculated values of the A C parameters are
  not greater than those in the Plan
• The orbital position corresponds to the nominal
  orbital position in the Plan
• If not, a submission is treated under Section IA

28
IMPLEMENTATION OF ALLOTMENTSSections I and IA of
Article 6 (4)

• Proposed assignments not in conformity with Part
  A of the plan shall be compatible with

30
IMPLEMENTATION OF EXISTING SYSTEMSSection IB of
Article 6 (2)

• Only existing systems for which the corresponding
  notices for recording in the Master Register were
  received by the Bureau after 29 August 1988 and
  having characteristics different from those in
  Part B need to be examined with respect to
  Plan/List
• Existing systems in Part B expire after 20 years
  from the entry into force of the Appendix 30B (16
  March 1990) and have been either entered in the
  List, as well as notified and brought into use,
  or have been cancelled

31
IMPLEMENTATION OF SUBREGIONAL SYSTEMS Section II
of Article 6 (1)

• All or part of the national allotments used by
  the subregional system shall be suspended for the
  life period of the subregional system unless it
  does not affect allotments or assignments
• The suspended national allotments will continue
  to be protected in the same way as other
  allotments in the Plan, for use in case of
  cessation of the subregional system

32
IMPLEMENTATION OF SUBREGIONAL SYSTEMS Section II
of Article 6 (2)

• The mutual interference between the subregional
  system and the suspended national allotments will
  not be taken into account for the life period of
  the subregional system
• The worst interference caused by either the
  subregional system or the suspended national
  allotments will be taken into account, but not
  both at the same time

33
IMPLEMENTATION OF SUBREGIONAL SYSTEMS Section II
of Article 6 (3)

ADDITIONAL USESSection III of Article 6 (2)

• To be implemented, the systems applying the
  procedures for additional use shall be compatible
  with
• Systems in Part A
• Systems in Part B
• Assignments in the List
