waas current geo performance
WAAS Current GEO Performance
  • Both WAAS GEOs (CRW and CRE) Currently Operating Nominally
    • CRW Failure Expected by end of July 2010
    • Daily Monitoring of CRW Performance shows no degradation of service at present
  • Preparing for single GEO (CRE) Coverage
    • Yearly maintenance of CRE Uplink stations completed early
    • GEO Uplink station receiver updated with improved firmware
expected impacts with crw failure
Expected Impacts with CRW Failure
  • Once CRW service is discontinued, WAAS service over CONUS and most of Alaska will be provided by a single GEO
    • WAAS Users Will Experience Outages During GEO Uplink Subsystem (GUS) Switchovers
      • Temporary Loss of Service Approximately 5 Minutes Per Event
      • Typically Occurs 4 – 5 Times Per Month
  • In NW Alaska there will be no WAAS service since the remaining GEO (CRE) does not provide service to NW Alaska
    • Users Will Still Have LNAV Service with GPS RAIM
    • En route / Terminal Reverts to RAIM
      • NW Alaska and the Western Edge of NAS in North Pacific

other impacts of crw failure
Other Impacts of CRW Failure
  • WAAS Program is accelerating implementation of a third GEO satellite (Gap-Filler)
    • Originally planned for operational use by Dec 2010
    • Accelerated Schedule projected to have GEO operational by Oct 2010 but will Increase Program costs by approximately 1.5 M
    • Addition of Gap-Filler GEO provides only limited coverage over Southeast Alaska
  • With a Single GEO (CRE) Operating WAAS performance more vulnerable to weak GPS constellation
    • Following example shows impact of a CRE GUS switchover at time when Critical GPS satellite (PRN 2) is unuseable
    • When a GUS Switchover occurs it takes upward of 6 hours before GEO can be used for ranging
mitigation activity status
Mitigation Activity Status
  • WAAS Program is accelerating acquisition of a Ranging capable GEO
    • Program office had completed a market survey for GEO satellites just prior to CRW failure
    • Efforts underway to establish a procurement vehicle for new GEO(s)
    • FAA is awaiting replacement solution from loss of CRW from GEO satellite provider (Lockheed Martin)
  • Former WAAS GEO (POR) has been identified as mitigation for loss of Service in Alaska
    • Program Office has started planning efforts for inclusion of this satellite back into WAAS
    • Testing being conducted to evaluate how to operate POR in the current WAAS configuration
expected coverage
Expected Coverage
  • Current Coverage
    • CRW (Intelsat) at 133° W
    • CRE (Telesat) at 107.3° W
  • Expected Coverage with Third WAAS GEO Operational October 2010
    • AMR (Inmarsat) at 98° W
  • Expected Coverage with POR
    • POR (Inmarsat at 178° E

10th International GBAS Working GroupWhere did we come from and where are we going

  • Today
    • First FAA approved system - Honeywell SLS4000 (Sept 2009)
    • Proliferation of GBAS worldwide
    • Common understanding of importance of Ionosphere
    • Use of common tools – Pegasus
    • Increased exchange of information between nations (MoAs)
  • 60+ Airlines have ordered GBAS

capable Boeing and Airbus aircraft

  • Current airlines GBAS equipped:

Air Berlin, TuiFly, Sonair, Air Vanatu,

Emirates

  • Over 15 countries have active GBAS

programs

summary
Summary
  • Single frequency coverage is good within the countries fielding SBAS
  • Dual frequency extends coverage outside reference networks & allows LPV operation in equatorial areas
  • Expanding networks into southern hemisphere could allow global coverage of land masses
  • Additional constellations allow even greater coverage with fewer stations

benefit updates for gbas cat ii iii faa acquisition
Benefit updates for GBAS CAT II/III - FAA Acquisition
  • CAT IIIa/b Precision Approach: supports the strategy to evolve towards a performance-based NAS by using a satellite based navigation system and onboard technologies.
  • Precision Approach Access: GBAS provides precision approach capability where siting constraints have prevented ILS from being implemented or CAT III implementation is cost prohibitive.
  • Removal of ILS Critical Areas: GBAS is not limited by the operational restrictions due to ILS critical areas and can reduce ground movement delays.
  • Wake Turbulence: GBAS can provide multiple approach procedures on a single runway with different glide slope angles reduction in separation by mitigating wake turbulence.
  • Closely Spaced Parallel Operations: GBAS has the capability of providing selectable glide paths, as well as displaced thresholds and providing the most accurate navigation to support all advancements in CSPO independent operations.
benefit updates for gbas cat ii iii faa acquisition52
Benefit updates for GBAS CAT II/III - FAA Acquisition
  • DCPS: GBAS provides differentially corrected positioning services within the terminal area to enable GBAS equipped users to fly complex RNAV/RNP procedures with higher availability.
  • Surface Navigation: In conjunction with ADS-B equipment, early provision of GBAS PNT services may enable positioning service for surface movement, navigation, and virtual tower operations.
  • RNAV/RNP: GBAS systems will enable early adoption of the navigation accuracy required in high density airspace for most mid-term and advanced concepts in the terminal environment.
  • User Transition: GBAS CAT I also provides an early opportunity for operational familiarity with the procedures prior to the availability of GBAS Cat II/III systems.
