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 INTERAGENCY GPS 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 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 = (+/-12 Mhz)  Protect GPS Signals from Interference caused by Other Systems  e.g., Ultra Wideband Transmissions, MSS

11 FEDERAL RADIONAVIGATION 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 TO GPS-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 TO GPS-BASED SERVICES  Maritime DGPS:  FOC Declared on March 15, 1999

15 DIFFERENTIAL GPS COVERAGE IN EUROPE

16 TRANSITIONING TO GPS-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
