ACP WGM Iridium Subgroup

• The Iridium Subgroup was formed in WG-M with the
  task to develop an implementation manual and a
  manual on detailed technical specifications, on
  the basis of the draft generic AMS(R)S SARPs that
  were developed by the ACP.
• From Recommendation 3/2 of the ACP Working Group
  of the Whole (21 - 29 June 2005) and in
  coordination between the Rapporteur of WG-M, the
  panel member nominated by the United States and
  the ACP Secretariat.
• Subgroup Tasks
• Develop the new Iridium technical manual in a
  timeframe that would support the suggested
  applicability date of the AMS(R)S SARPs by
  November 2007
• Create an implementation manual to provide
  guidance to States on commissioning the system
• Identify any validation requirements associated
  with the Iridium technical manual and conduct
  appropriate validation if necessary
• Establish a documentation control system to
  identify and manage the core documents
• Coordinate with other ICAO panels as appropriate
  through the ICAO Secretariat and
• Secure broadest participation from industry in
  the activities of the sub-group.

6
ACP WGM Iridium Subgroup

• Meeting overviews
• ACP WGM Iridium 5 22-24 August 2006
• Reviewed status of AMS(R)S SARPs responses from
  states
• Reviewed combined Technical and Implementation
  Manual
• Reviewed Satcom Availability Analysis from
  Future Communications Study

  in WGN-1 activities

7
ACP WGM Iridium Subgroup

• Key Issues the Iridium Subgroup has addressed
• Understanding and applying the new ICAO
  philosophy of generic or performance-based
  SARPs coupled with system-specific Manual(s)
• SARPs provide performance requirements, rather
  than system technical specifications
• A separate document for each specific system
  implementation provides technical specifications
• What is the required and appropriate content of
  Technical and Implementation manuals
• Technical manual provides system technical
  specifications and demonstrates compliance with
  SARPs
• Implementation manual provides guidance for
  system implementation

8
ACP WGM Iridium Subgroup

• Key Issues the Iridium Subgroup has addressed
• Whether, and how, to combine the Technical and
  Implementation manuals into one document
• Current version is now a single document,
  restructured to eliminate redundancy and create a
  more generic manual to enable flexibility for
  future amendments if necessary, and to provide
  material that can be used for other systems
  manuals (e.g. Inmarsat, MTSAT)
• How to present Iridium performance vs. SARPs
  requirements and what validation is required
• Iridium performance is compared to SARPs
  requirements in a Table
• Validation of Iridium performance is documented
  in a separate validation report
• How to consider Iridium as a subnetwork within an
  end-to-end communications network
• The draft AMS(R)S SARPs cover the satellite
  subnetwork
• End-to-end performance is considered within the
  ATN structure inclusion of Iridium as a
  subnetwork within ATN SARPs is being considered

ACP WGM Iridium Subgroup

• Overview of Iridium Manual Contents
• The Technical manual and implementation manuals
  have been combined into one manual.
• This consolidated manual contains information
  about aeronautical mobile satellite
  communications, using the Iridium Satellite
  Network, including applications, potential
  benefits, user requirements, system architecture,
  interoperability and technical characteristics,
  as well as space, ground and airborne equipment.
  
• Information on status of development and ICAO
  activities (institutional arrangements, spectrum
  availability, SARPs and networking) is also
  included.

ACP WGM Iridium Subgroup

• Overview of Iridium Manual Contents
• Chapter 1 Introduction
• includes potential benefits that can be expected
  from the use of a satellite communication service
  for AMS(R)S and an overview of how the Iridium
  Satellite Network supports AMS(R)S)
• Chapter 2 Services, User requirements and
  Operational
• Chapter 3 Standardization activities
• Chapter 4 ICAO Activities
• Chapter 5 Iridium Satellite Network
• Chapter 6 Iridium AMS(R)S System

11
ACP WGM Iridium Subgroup

• Overview of Iridium Manual Contents
• Chapter 8 Comparison of AMS(R)S SARPs and
  Expected Iridium Performance
• Chapter 9 Implementation Guidance
• A Validation manual has been developed to provide
  information on how the Iridium system complies

• Each of the AMS(R)S requirements are addressed
  to show validation method and details of
  validation.

12
ACP WGM Iridium Subgroup

• Status of Iridium Subgroup Activities
• Continue refining the Iridium Manual and
  complete final draft
• Including validation report
• Work with ACP WGN Subgroup N1 to enable
  inclusion of Iridium as an ATN air-ground
  subnetwork

  SARPs
• Next meeting will be 24-26 October 2006 (ICAO
  HQ)
• Schedule
• The target date for completion of the Iridium
  manual is to coincide with ANC meeting to adopt
