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

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)

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