GPS POLICY AND PLANNING

1. GPS POLICY AND PLANNING Mr. Joe Canny US Department of Transportation Presented at IISC Meeting December, 1999

2. Overview • Interagency GPS Executive Board • GPS Modernization • FY00 Budget Impact on Modernization • International Consultations • Spectrum Issues • Federal Radionavigation Plan

3. INTERAGENCY GPS EXECUTIVE BOARD (IGEB) • Co-Chairs - Department of Transportation - Department of Defense • Participants - Department of State - Department of Interior - Department of Commerce - Department of Justice - Department of Agriculture - NASA - Joint Chiefs of Staff

4. INTERAGENCYGPS EXECUTIVE BOARD • Meeting Aug ‘99 • Reviewed: • Options for L5 Signal Implementation • GPS Modernization Alternatives • International Activities • Status of National GPS Plan • Meeting Nov ’99 • Reviewed • FY00/01 Budget Impacts on GPS Modernization • International Activities • Status of National GPS Plan • Next Meeting end of Jan ‘00

5. GPS MODERNIZATION • Jan ‘99 White House Memo: • Defined Additional Civil Signals • 2nd civil signal at L2 • 3rd signal (L5) at 1176.45 Mhz (safety-of-life) • IGEB to resolve technical/funding problems by August ‘99 for implementing L5 • IGEB Formed L5 Implementation Steering Group: • Established Working Groups to Assess Technical & Procedural Measures for Sharing • Define Signal • Preserve Military and Civil Operational Capabilities • Minimize total cost to the US Government • International Outreach • Decision Options Presented to IGEB on August 16, 1999 • Final Report Submitted October 1999 • Follow on work to focus on EMC testing

6. FEATURES/BENEFITS OF L5 • Available on BLK IIF satellites beginning with Launches in 2005 • 6 dB stronger signal than L1 • 20 MHz bandwidth • More robust signal structure than L1 • ARNS protected band (only need RNSS allocation)

7. FEATURES/BENEFITS OF L5 • Provides greater interference mitigation worldwide • Provides greater reliability for safety-of-life applications, including civil aviation worldwide • Allows greater position accuracies for all types of applications, including aviation precision approaches worldwide • L5 + L1 will allow avionics in aircraft to correct for ionosphere induced errors • Will reduce the need for ground infrastructure investments

8. FY ‘00 BUDGET IMPACT ON MODERNIZATION • Congressional adjustment of FY00 Transportation budget - no funding for civil GPS modernization • President Clinton Statement that we will identify ways to reduce impact of budget cut • U.S. Remains committed to modernizing GPS and adding new civil signals

9. INTERNATIONAL CONSULTATIONS • European Union • Resolution to begin Galileo design phase – Jun 99 • Negotiation mandate with US, Russia, others – Oct 99 • 6 rounds of consultations – Nov 99 most recent • Focus on encouraging Galileo to be GPS-like to best serve interests of international user community • Consistent with a number of basic principles • Seamless, global interoperability • Open Signal Structure • No direct user fees for basic civil and public safety services • Open Market Access • Japan • Joint Statement signed in Sept 98 • Strong Cooperative Relationship Developed • Working Groups Met September 99 • Int’l Policy and Public Safety, Transportation Applications, and Commercial and Scientific Use and Development

10. PROTECTING SPECTRUM • WRC 2000 GPS ISSUES • Protect L1 Band from MSS incursions • Urge states to clear L1 Band of footnotes for non-ARNS systems • Space-to-Space (s-s) Allocation for L1 and L2 • Expands from Space-to-Earth (s-E)to (s-E and s-s). • Obtain RNSS Allocation of new GPS Frequency at L5 = 1176.45 (+/-12 Mhz) • Protect GPS Signals from Interference caused by Other Systems • e.g., Ultra Wideband Transmissions, MSS

11. FEDERALRADIONAVIGATION PLAN • Now called 1999 Federal Radionavigation Plan • Need to address post 1998 decisions • Anticipate Publication in early 2000 • Current Policy and Plans • GPS • Transitioning to GPS-based Services

12. GLOBAL POSITIONING SYSTEM • Presidential Decision Directive/FRP • GPS SPS Available Worldwide Free of Direct User Charges • Augmented GPS planned to be the Primary U.S. Government operated Radionavigation System for the Foreseeable Future

13. TRANSITIONING TOGPS-BASED SERVICES • WAAS/CAT I:Initial Capability September 2000 • LAAS/CAT II/III:Date to begin Service uncertain • Based on user decisions to transition to SATNAV, as well as Budget Considerations

14. TRANSITIONING TOGPS-BASED SERVICES • Maritime DGPS: • FOC Declared on March 15, 1999

15. DIFFERENTIAL GPS COVERAGE IN EUROPE

16. TRANSITIONING TOGPS-BASED SERVICES • Nationwide DGPS • $5 M Appropriated in FY00 • Establishes 15 new sites • Bridges the coverage gap in the mid-continent • Nationwide implementation planned by end of 2002

17. PHASEDOWN OF LAND-BASED SYSTEMS • Loran-C • Approved Policy on Loran-C Pending • $10.2M Appropriated in FY00 to Maintain Loran-C • Administration Evaluating Long-term Disposition • 1999 FRP to be Published Following Loran Decision

18. SUMMARY • U.S Remains Committed to GPS • SPS Available Free of Direct Charge • GPS Modernization (additional civil signals) • Maritime DGPS FOC March 1999 • WAAS IOC in September 2000 • Full Nationwide DGPS Service by 2003 • Spectrum Protection Critical for Satellite-based Navigation Services • Final Decision on Loran-C Pending • Publish 1999 FRP
