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

INTERAGENCY GPS EXECUTIVE BOARD 1. Meeting Aug ‘ 99 1. Reviewed: • • Options for L 5 Signal Implementation GPS Modernization Alternatives International Activities Status of National GPS Plan 2. Meeting Nov ’ 99 1. Reviewed • FY 00/01 Budget Impacts on GPS Modernization • International Activities • Status of National GPS Plan Ø Next Meeting end of Jan ‘ 00 4

GPS MODERNIZATION Ø Jan ‘ 99 White House Memo: v Defined Additional Civil Signals • 2 nd civil signal at L 2 • 3 rd signal (L 5) at 1176. 45 Mhz (safety-of-life) v IGEB to resolve technical/funding problems by August ‘ 99 for implementing L 5 Ø IGEB Formed L 5 Implementation Steering Group: v 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 Ø Decision Options Presented to IGEB on August 16, 1999 v Final Report Submitted October 1999 v Follow on work to focus on EMC testing 5

FEATURES/BENEFITS OF L 5 Ø Available on BLK IIF satellites beginning with Launches in 2005 Ø 6 d. B stronger signal than L 1 Ø 20 MHz bandwidth Ø More robust signal structure than L 1 Ø ARNS protected band (only need RNSS allocation) 6

FEATURES/BENEFITS OF L 5 Ø Provides greater interference mitigation worldwide Ø Provides greater reliability for safety-of-life applications, including civil aviation worldwide Ø Allows greater position accuracies for all types of applications, including aviation precision approaches worldwide v. L 5 + L 1 will allow avionics in aircraft to correct for ionosphere induced errors v. Will reduce the need for ground infrastructure investments 7

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

INTERNATIONAL CONSULTATIONS Ø European Union v. Resolution to begin Galileo design phase – Jun 99 • Negotiation mandate with US, Russia, others – Oct 99 v 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 Ø Japan v. Joint Statement signed in Sept 98 v. Strong Cooperative Relationship Developed v. Working Groups Met September 99 • Int’l Policy and Public Safety, Transportation Applications, and Commercial and Scientific Use and Development 9

PROTECTING SPECTRUM Ø WRC 2000 GPS ISSUES v. Protect L 1 Band from MSS incursions v. Urge states to clear L 1 Band of footnotes for non-ARNS systems v. Space-to-Space (s-s) Allocation for L 1 and L 2 • Expands from Space-to-Earth (s-E)to (s-E and s-s). v. Obtain RNSS Allocation of new GPS Frequency at L 5 = 1176. 45 (+/-12 Mhz) Ø Protect GPS Signals from Interference caused by Other Systems ve. g. , Ultra Wideband Transmissions, MSS 10

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

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

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

TRANSITIONING TO GPS-BASED SERVICES Ø Maritime DGPS: v. FOC Declared on March 15, 1999 14

DIFFERENTIAL GPS COVERAGE IN EUROPE 15

TRANSITIONING TO GPS-BASED SERVICES Ø Nationwide DGPS v$5 M Appropriated in FY 00 • Establishes 15 new sites • Bridges the coverage gap in the mid-continent v. Nationwide implementation planned by end of 2002 16

PHASEDOWN OF LAND-BASED SYSTEMS Ø Loran-C v. Approved Policy on Loran-C Pending v$10. 2 M Appropriated in FY 00 to Maintain Loran-C v. Administration Evaluating Long-term Disposition v 1999 FRP to be Published Following Loran Decision 17

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