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
• Intl 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
