  Conference on the Use of the Geostationary-Satelli
  te Orbit and the Planning of Space Services
  Utilizing It (WARC ORB-88).

Appendix 30B FSS PLAN

• 6 / 4 GHz
• (300 MHz)
• 6725 - 7025 MHz (up)
• 4500 - 4800 MHz (down)

13 / 10-11 GHz (500 MHz) 12.75 - 13.25 GHz
(up) 10.70 - 10.95 GHz (down) 11.20 - 11.45
GHz (down)
17
TYPES OF SYSTEMS

• The FSS Plan contains two types of systems
• PART A systems
• National Allotments
• PART B systems
• Existing Systems
• Two other types of systems can be implemented
• Subregional Systems
• Additional Uses

18
ALLOTMENT

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

19
ALLOTMENT

• Characteristics of the national allotments such
  as nominal orbital position, PDA, service arc and
  ellipse parameters are contained in Article 10 of
  Appendix 30B. 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/p
  lans/ap30b).

20
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

21
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

22
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

23
LIST OF ASSIGNMENTS

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

24
TECHNICAL CRITERIA

• C/N ratio of 16 dB
• Aggregate C/I ratio of 26 dB
• Single entry C/I ratio of 30 dB

25
TECHNICAL CRITERIA

• 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.

26
PREDETERMINED ARC (PDA)

• 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

27
PREDETERMINED ARC (PDA)

• 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.

28
PREDETERMINED ARC (PDA)

• 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.

29
PREDETERMINED ARC (PDA)

• 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)

30
GENERALIZED PARAMETERS

• 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

31
GENERALIZED PARAMETERS

• 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

32
IMPLEMENTATION OF ALLOTMENTS

• 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

33
IMPLEMENTATION OF ALLOTMENTS

• The macro segmentation concept was introduced as
  a means to avoid coordination during the
  implementation of an allotment. Whenever 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 (averaged over the worst 4 kHz) to
  average (defined over the necessary bandwidth of
  the modulated carrier) is greater than 5 dB. The
  low density carriers are those for which this
  ratio is less than 5 dB.

34
IMPLEMENTATION OF ALLOTMENTS

• 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

35
IMPLEMENTATION OF ALLOTMENTS

• Proposed assignments not in conformity with Part
  A of the Plan shall be compatible with
• systems in Part A
• systems in Part B
• assignments in the List

36
IMPLEMENTATION OF EXISTING SYSTEMS

• To be recorded in the List, the existing systems
  contained in Part B shall be compatible with
• systems in Part A
• systems in Part B
• assignments in the List

37
IMPLEMENTATION OF EXISTING SYSTEMS (2)

• Only existing systems having characteristics
  different from those in Part B and which were
  received by the BR after 29 August 1988 need to
  apply the procedures
• Existing systems in Part B expire after 20 years
  from the entry into force of the Appendix 30B (16
  March 1990)

38
IMPLEMENTATION OF SUBREGIONAL SYSTEMS

• 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

39
IMPLEMENTATION OF SUBREGIONAL SYSTEMS (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

40
IMPLEMENTATION OF SUBREGIONAL SYSTEMS (3)

• To be implemented, the subregional system shall
  be compatible with
• systems in Part A
• systems in Part B
• assignments in the List

41
IMPLEMENTATION OF ADDITIONAL USES (1)

• The procedures for additional uses may be applied
  provided that the proposed assignments have a
  maximum period of validity of 15 years

42
IMPLEMENTATION OF ADDITIONAL USES (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

43
NEW ALLOTMENT FOR A NEW MEMBER STATE

• A new Member State can obtain a national
  allotment in Part A of the Plan. Required
  information
• geographical coordinates of 10 test points (max.)
• height above sea and rain zone (conformity with
  Rec. ITU-R P.837-3 is verified) of each test
  point
• any special requirement, other than a fixed
  orbital position

44
NOTIFICATION OF ASSIGNMENTS

• Any assignment for which the relevant procedure
  of implementation has been successfully applied
  shall be notified in accordance with Article 11
  of the RR
• A PDA of zero degree (operational stage) shall be
  associated with this assignment
