GNSS Aviation Integrity

• Using ICAO GNSS Implementation Strategy and ICAO
  Standards and Recommended Practices
• GPS Aviation Use Approved for Over a Decade
• Aircraft Based Augmentation Systems (ABAS)
  (e.g. RAIM)
• Space Based Augmentation System (SBAS) since 2003
• Wide Area Augmentation System (WAAS) augmenting
  GPS
• Development of GNSS Ground Based Augmentation
  System (GBAS) Continues
• Local Area Augmentation System (LAAS)
• GNSS is Cornerstone for National Airspace System

GPS (ABAS) Aviation Receivers

• Over 16,000 Commercial Air Carrier Instrument
  Flight Rated (IFR) GPS Receivers Sold (as of
  2003)
• Additional 70,000 80,000 General Aviation IFR
  GPS receivers sold
• U.S. manufacturer sales only (does not include
  units limited to visual situational awareness)

Space Based Augmentation System (e.g. WAAS)

• Enhanced Navigation for All Phases of Flight
• Enroute, Arrival, and Departure Provides
  Navigation Services to Users Not Currently Served
  by Land Based Navigation Aids
• Increases Availability of GNSS
• Vertically Guided Aircraft Approach
• Enhances Safety by Providing Vertical Guidance
• No Ground Hardware Required at Airport
• Allows Instrument Operations to All Capable
  Airports
• Supports Every Runway in Coverage Area
• Provides Safety of Life Integrity Services today
• Use Expanding Globally
• SBAS Can Augment Multiple Satellite Navigation
  System Constellations

SBAS Avionics

• Currently Available
• Garmin GNS-480/CNX-80 4000 units sold
• In Development
• Garmin 430/530 Upgrade Available Fall 2006
• 50,000 units sold and eligible for upgrade
• Free Flight Available 2006
• Panel Mount Receiver and LPV capable sensor
• Avidyne, Chelton, CMC, Universal, Thales, and
  Honeywell expect to have units available
  2006/2007
• Development of Rockwell Collins Unit
• Supports high end users, available Nov 2006
• WAAS Upgrade for Challenger 604 (FAA flight
  inspection aircraft) available June 2007

Ground-Based Augmentation System (GBAS)

• U.S. Approach to ICAO Strategy for Interoperable
  GBAS is Local Area Augmentation System (LAAS)
• Provides Navigation Signal to Support Most
  Demanding Approach Requirements
• One LAAS Ground Station Can Cover Entire Airport
  to Provide Precision Guidance
• Approach and Departure Procedures to All Runway
  Ends
• Surface Movement (Taxi operations)

GBAS International Cooperation

• International Service Providers Need Precision
  Approach capability (200 to zero foot Decision
  Height)
• FAA, Airservices Australia, AENA/Spain, and
  DFS/Germany Have Ongoing Contract Activities
• International GBAS Working Group established
• With European Service Providers, EUROCONTROL and
  Industry
• Boeing Airbus Joined in Support of GBAS
• Boeing B-737NG Certified With GBAS Avionics
• Airbus A-380 to be Certified
• International GBAS Development Activities
• Airservices Australia Interested in cooperation
  with FAA to Leverage U.S. GBAS Technology
  Investments to provide initial ops capability
• Germany and Spain Interested in use of resulting
  product
