  1. FAA Global Navigation Satellite System (GNSS)Program Plans and StatusGPS/WAAS/LAAS Leo Eldredge, GNSS Program Manager Federal Aviation Administration (FAA) Space Enterprise Council March 14, 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 • Enable Performance-Based Navigation Services Capability RNAV & RNP • Position Navigation Timing (PNT) is a Critical Enabler for NextGen • Legacy Services With Negative Benefits/Cost Will Eventually Be Removed

  4. Global Navigation Satellite System (GNSS)

  5. Global Positioning System (GPS) Space Segment • 24 Orbit Slots • 6 Orbital Planes • 4 Satellites Per Plane (Nominal) • 55 Degrees Inclination • Orbit at 10,800 Miles • Orbits Once Every 12 Hours Control Segment • 6 GPS Monitor Sites • 11 NGA Monitor Sites • 2 Operational Control Centers User Segment • Military & Civil Receivers • Precise Positioning Service (PPS) • Standard Positioning Service (SPS)

  6. FAA Satellite Navigation Program

  7. Aviation Benefits LNAV/VNAV 350’ LPV 250’ LPV 200’ 3o

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

  9. PanAmSat 133°W Telesat 107°W GEO Satellites

  10. Vertical Service Coverage

  11. WAAS Approach Procedures LPVs: 1028 LNAV/VNAVs: 1275 WAAS Procedures to be Published to All Instrument Runways in the NAS by 2018

  12. WAAS Avionics Status • General Aviation • Over 28,000 WAAS Avionics Units Sold • Business & Regional Aircraft FMS Avionics • Rockwell-Collins: Expecting Approval in FY2008 • Canadian Marconi Corporation: by December 2008. • Universal Navigation Systems: Approved in 2007 • Air Carrier & Cargo Aircraft • Southwest Airlines Equipping 200 Boeing 737 with GPS/WAAS • Federal Express (FEDEX) Equipping 300 Aircraft with WAAS Avionics • Helicopter Aircraft Implementing WAAS

  13. WAAS In Use By Non-Aviation Users

  14. Local Area Augmentation System (LAAS)

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

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

  17. 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)

  18. FAA Priorities for GPS • Sustainment of the GPS Constellation to Meet Commitments in the GPS Standard Positioning Service Performance Standard (SPS PS) • Baseline GPS Modernization Schedule to Support Long Term Planning and Decision Making • Provision of a Constellation of Dual Frequency (L1 & L5) Satellites • Combination GPS Block IIF and GPS-III Satellites • Significant Improvement in Availability and Reliability • Continually Look at Improved Service Through GPS Modernization • Larger Constellation Size Would Improve Service for Aviation • Improved Accuracy, Availability, and Integrity
