  1. U.S. Space-Based Positioning, Navigation, and Timing Programs and Policy Steve SidorekLegislative Affairs Advisor September 17, 2009

  2. Overview Global Positioning System U.S. Policy Congressional Outreach & Funding 1

  3. GPS is a Critical Component of the Global Information Infrastructure Satellite Operations Aviation Surveying & Mapping Precision Agriculture Communications Power Grids Disease Control Trucking & Shipping Personal Navigation Fishing & Boating Oil Exploration

  4. Keys to the Global Success of GPS Program Stability and Performance Policy Stability and Transparency Private Sector Entrepreneurship and Investment 3

  5. The Global Positioning System • Baseline 24 satellite constellation in medium earth orbit • Global coverage, 24 hours a day, all weather conditions • Satellites broadcast precise time and orbit information on L-band radio frequencies • Two types of service: • Standard (free of direct user fees) • Precise (U.S. and Allied military) • Three segments: • Space • Ground control • User equipment

  6. GPS Constellation Status 30 Operational SatellitesAs of August 27, 2009 (Baseline Constellation: 24) • 11 Block IIA • 12 Block IIR • 7 Block IIR-M • First Block IIF launch in spring 2010 • 12 Block IIF satellites planned • GPS continues to meet/exceed civil service performance commitments

  7. Increasing System Capabilities w Increasing Defense / Civil Benefit GPS Modernization Program Block IIA/IIR Block IIR-M, IIF Block III • Basic GPS • Standard Service • Single frequency (L1) • Coarse acquisition (C/A) code navigation • Precise Service • Y-Code (L1Y & L2Y) • Y-Code navigation • IIR-M: IIA/IIR capabilities plus • 2nd civil signal (L2C) • M-Code (L1M & L2M) • IIF: IIR-M capability plus • 3rd civil signal (L5) • Anti-jam flex power • Backward compatibility • 4th civil signal (L1C) • Increased accuracy • Increased anti-jam power • Assured availability • Navigation surety • Controlled integrity • Increased security • System survivability

  8. Benefits of GPS Modernization System-wide improvements to meet increasing civil, commercial, and military demands • Higher standalone performance, accuracy, etc. • More robust against interference • Improved indoor, mobile, and urban use • Provides separate more secure military signal • Interoperability with other Global Navigation Satellite Systems

  9. GPS III Update • Contract for GPS III-A satellites awarded, May 2008 • Selective Availability feature eliminated • Contracts for Next-Generation Operational Control Segment (OCX) awarded, Nov 2007 • Will implement full functionality of L2C and L5 • Future increments of GPS III will incorporate additional capabilities • As technology matures and new requirements are validated

  13. Congressional Outreach Efforts • Educational meetings with Capitol Hill staff • Monthly newsletter • Hill outreach events • March 2008, April 2009 • Future event anticipated in Fall 2009 • Web page tailored for congressional staff (PNT.gov/congress) • Reports to Congress • Tracking of legislation and program funding status 12

  14. Fiscal Year 2010 Program Funding Status of Appropriations

  15. Summary • GNSS use continues to expand with many new applications emerging • GPS program and policy provide stable foundation for continued market innovation • Modernization will further improve service • Executive Committee actively involved in policy implementation • Congressional outreach efforts ramping up • Civil GPS funding line critical to program success
