FAA Civil Aviation Satellite Navigation
UpdateWAAS/LAAS

• Leo Eldredge, GNSS Program Manager
• Federal Aviation Administration (FAA)
• ICNS Conference
• May 5 2008

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
