  1. FAA Civil Aviation Satellite Navigation UpdateWAAS/LAAS Leo Eldredge, GNSS Program Manager Federal Aviation Administration (FAA) ICNS Conference May 5 2008

  2. Peak Aircraft Traffic Over The US

  3. Future Planning Assumptions • By 2025 , Aviation is Expected to Increase By a Factor of 2.7 • The NAS Will Transition to Satellite Navigation Technology • Provide Performance-Based Navigation Services to Enable RNAV & RNP • Position Navigation Timing (PNT) is a Critical Enabler for NextGen • New Navigation Services Must Be Cost-Beneficial • Legacy Services With Negative Benefits/Cost Will Eventually Be Removed Cost • Resources Will Be Limited

  4. Global Navigation Satellite System (GNSS)

  5. FAA Satellite Navigation Program

  6. WAAS Architecture 38 Reference Stations 3 Master Stations 4 Ground Earth Stations 2 Geostationary Satellite Links 2 Operational Control Centers

  7. PanAmSat 133°W Telesat 107°W Geostationary Satellites (GEO) • Provides Dual Coverage Over United States

  8. WAAS Vertical Service Coverage

  9. WAAS LNAV and RNP Coverage

  10. WAAS Accuracy Performance * Use of GPS vertical not authorized for aviation without augmentation (SBAS or GBAS) WAAS Performance evaluated based on a total of 1,761 million samples (or 20,389 user days)

  11. Summary of RNAV(GPS) - Minima LPV - Localizer Performance with Vertical WAAS avionics minima LNAV/VNAV – Lateral Navigation With Vertical Baro-VNAV, or WAAS Avionics LNAV - Lateral Navigation Non-Precision Approach (NPA)

  12. WAAS Approach Procedures As of April 10, 2008 • 1,051 LPVs • 602 LPVs to non-ILS runways • 449 LPVs to ILS runways • 14 LPV’s published • to <250’ Decision Altitute WAAS Procedures to be Published to All Instrument Runways in the NAS by 2018

  13. WAAS Avionics Status • General Aviation Aircraft Are Equipped With Garmin GPS Receivers • Total WAAS Equipped Users ~30,000 • Rockwell-Collins: FAA Flight Inspection Challenger Aircraft Approval – August 2007 • Canadian Marconi: Contract To Integrate WAAS Sensor Into FAA Global 5000 Aircraft To Complete In 2008 • Universal Avionics: Developing WAAS Enabled Capability In Dual Thread UNS-1 Flight Management System Expected in 2007

  15. GPS Program Evolution Space Segment Modernized(Block IIR-M) • 2nd civil signal (L2C) • M-Code signals (L1M, L2M) • Anti-jam flex power Modernized(Block IIF) • 3rd civil signal (L5) GPS III(Block III) • Increased accuracy • Increased A/J power • Signal integrity • Search and Rescue • L1C civil signal common w/Galileo, QZSS, & possibly GLONASS Legacy(Block IIA/IIR) • Std Service (≤ 6 meters RMS SIS SPS URE) • Single frequency (L1) • Coarse acquisition (C/A) code navigation • Precise Service (≤ 2.6 m 95% URE PPS at Zero AOD) • Y-Code (L1Y & L2Y) • Y-Code navigation Ground Segment Legacy • TT&C • L1 & L2 monitoring Upgraded(AEP) • IIR-M IIF TT&C • WAGE, AII, LADO • NMCS/AMCS Modernized(OCX V1) • New Architecture • Signal Monitoring GPS III(OCX V2) • GPS III TT&C • Real-Time C2

  16. Galileo (EU) GLONASS COMPASS (China) Future GNSS Considerations GPS Modernization

  17. Local Area Augmentation System (LAAS) • Precision Approach For CAT- I, II, III • Multiple Runway Coverage At An Airport • Terminal Area Procedures for Arrival and Departure

  18. Current Activities • Integrity Analysis and Prototype Development • LAAS System Design Approval (SDA) Process • LAAS Operational Implementation at Memphis Airport • International Cooperation and Development • CAT-III Research & Development Activities

  19. Agana, Guam LAAS/GBAS International Efforts Rio De Janeiro, Brazil Malaga, Spain Sydney, Australia Frankfurt, Germany Memphis, Tenn. Bremen, Germany

  20. Summary • The FAA is Implementing Satellite Navigation Systems Needed to Support Performance Based Navigation and NextGen • The WAAS Program Has Matured Through Development and is Rapidly Progressing Through Operational Implementation • The First Certified LAAS is Expected In Late 2008 • Satellite Navigation is a Cornerstone of the Next Generation Air Transportation System (NextGen)
