Brief Program History
U.S. Department of Transportation
Research and Innovative Technology Administration

• Inland NDGPS Augmentation Developed as Extension
  of Maritime DGPS
• Provides real-time differential correction
  proven sub-meter accuracy 99 availability
• Provides single coverage on the ground over 92
  of CONUS and double coverage over 65 of CONUS
• Authorized in 1988 (P.L. 105-66) operated by
  U.S. Coast Guard under multiagency MOA
• DOT funded from multiple agencies under FRA
  program management (53M, FY98-06)

Brief Program History (2)
U.S. Department of Transportation
Research and Innovative Technology Administration

• The NDGPS Assessment
• FY07 zeroed out of FRA budget
• October 2006 PNT EXCOM action DOT complete
  assessment of the need for inland component of
  NDGPS
• FY07/08 RITA assessment in support of EXCOM
  action
• Federal Register Notice
• Independent Assessment (ARINC)
• Letter to Agencies
• Recommendations accepted by ESG 01/23/08
• Endorsed by EXCOM 03/20/08

National Space-Based PNT ExecCom Action
U.S. Department of Transportation
Research and Innovative Technology Administration

• Action DOT complete assessment of the need for
  inland component of NDGPS
• Final resolution to be determined by
• interagency requirements
• level of support
• If there were no transportation requirements or
  other Federal user requirements, DOT intended to
  develop decommissioning plan for NDGPS
• DOT cost share with other agencies possible if
  there is a transportation requirement

Assessment Affirms Requirements
U.S. Department of Transportation
Research and Innovative Technology Administration

• Assessment affirms operational requirements for
  inland NDGPS
• Transportation operational requirements
• Federal Highway Administration (FHWA)
• on behalf of state and local DOT stakeholders
• routine use in Federal-Aid Program
• survey, construction, quality, asset management
• Federal Railroad Administration (FRA)
• safety system requirements (positive train
  control, track defect location)
• Association of American Railroads
• baseline reference for positive train control
• National Governors Association
• use by state DOTs, resource management

Assessment Affirms Requirements (2)
U.S. Department of Transportation
Research and Innovative Technology Administration

• Assessment affirms operational requirements for
  inland NDGPS
• Other Federal operational requirements
• Department of Agriculture (NCRS, Forest Service)
• High-accuracy positioning/repeatability
• Fire services and enforcement
• Department of Commerce (NOAA NWS, NGS)
• Continuously Operating Reference Stations
• Weather forecasting
• Department of the Interior (BLM, NPS, USGS)
• High-accuracy positioning
• Fire services and enforcement
• Numerous natural resource stakeholders

Assessment Affirms Requirements (3)
U.S. Department of Transportation
Research and Innovative Technology Administration

• Assessment affirms operational requirements for
  inland NDGPS
• State/local and private sector operational
  requirements
• Civil GPS Services Interface Committee (CGSIC)
  U.S. States and Localities Subcommittee
• State Departments of Transportation, Natural
  Resources, Environmental Protection, Agriculture,
  Parks
• Multiple states and counties also responded
• Private/Non-Profit Requirements
• U.S. GPS Industry Council
• National Precision Farming Association
• Professional Land Surveyors

Assessment Affirms Requirements (4)
U.S. Department of Transportation
Research and Innovative Technology Administration

• Assessment results affirm research needs for
  inland NDGPS
• Transportation research requirements
• Federal Highway Administration (FHWA)
• Federal Railroad Administration (FRA)
• Association of American Railroads
• Alliance of Automobile Manufacturers
• Advocates for Highway and Auto Safety

• Assessment affirms no other existing PNT
  augmentation meets accuracy requirements for
  multiple terrestrial applications

10
Recommendations Accepted by ESG
U.S. Department of Transportation
Research and Innovative Technology Administration

• Ratify inland NDGPS as a national utility
• Reaffirm DOT sponsorship
• Determine funding required to deploy IOC/FOC

• DOT to lead interagency team to develop new
  program and business plan
• Jointly develop a fund-sharing mechanism among
  Federal Agencies with requirements
• Inclusion in Department/Agency FY10 budgets
  required
• System at risk due to deferred equipment refresh
• Free of user fees, per U.S Space-Based PNT Policy

11
NDGPS Funding, FY 08-09
U.S. Department of Transportation
Research and Innovative Technology Administration

• DOT/RITA FY08 Funding 4.6M
• RITA agreed to be interim program sponsor
• Existing system operations and Maintenance
• (OM) only
• No construction/expansion/upgrade for NDGPS
  sites in FY 07/08
• Pass-through to U.S. Coast Guard for OM
• DOT/RITA FY09 Funding 4.6M
• Pass-through to U.S. Coast Guard for OM
• Insufficient to meet OM requirements

Projected NDGPS Funding NeedsFY09
RecapitalizationUSCGDOT Estimates
U.S. Department of Transportation
Research and Innovative Technology Administration

• FY09 Shortfall
• 4.6M as placeholder insufficient for OM
• Shortfall 0.8M
• Recapitalization (required in FY09 for any
  operational scenario)
• 3.5M
• Equipment refresh required for ongoing operations
  (deferred maintenance)
• Three years behind Maritime DGPS
• Future estimates based on completing
  recapitalization (proven reduced OM costs)
• Total Additional Need 4.3M

13
Projected NDGPS Funding Needs FY10 and
OutyearsUSCGDOT Estimates
U.S. Department of Transportation
Research and Innovative Technology Administration

• Current System no build-out
• 5.9M average annual operations and maintenance
  (OM) only
• Complete Initial Operating Capability (IOC) 8
  sites
• 3.4M capital costs
• 6.2M annual (OM)
• Complete Full Operating Capability (FOC) 20
  sites
• 19.0M capital costs
• 6.5M annual OM
