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 (L 1 & L 5) 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 Global Navigation Satellite System (GNSS) Program Plans and Status February 28, 2008 Federal Aviation Administration 18
