Bottom Line

• DOT Has Decided to Continue Inland NDGPS OperationsDOT will continue as Executive Agent

• Next Steps for Interagency Team 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

FY09 O&M remains underfunded

Free of user fees, per U.S Space-Based PNT Policy

Brief Program History

• Inland NDGPS Augmentation Developed as Extension of Maritime DGPS

• Provides real-time differential correction; proven sub-meter accuracy; provides 1 -2 meter accuracy 98% of time; 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)

• 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

Assessment Affirms Requirements

• Assessment affirms operational requirements for inland NDGPSTransportation 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 Governor’s Association

» use by state DOTs, resource management



08/05/08 7

Assessment Affirms Requirements (2)

• Assessment affirms operational requirements for inland NDGPSOther Federal operational requirements:

Department of Agriculture (NCRS, Forest Service)

» 1 meter real-time positioning and navigation

» Fire management and safety

Department of Commerce (NOAA – NWS, NGS)

» Continuously Operating Reference Stations

» Weather forecasting

Department of the Interior (BLM, NPS, USGS)

» 1 meter real-time positioning and navigation

» Fire management and safety

Numerous natural resource stakeholders

• Assessment affirms operational requirements for inland NDGPSState/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



08/05/08 9


• Assessment results affirm research needs for inland NDGPSTransportation 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

08/05/08 10

Recommendations Accepted by EXCOM

• Ratify inland NDGPS as a national utilityReaffirm DOT sponsorshipDetermine 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

NDGPS Funding, FY 08-09

• DOT/RITA FY08 Funding = $4.6M Existing system operations and Maintenance (O&M) only No construction/expansion/upgrade for NDGPS sites in FY 07/08 Pass-through to U.S. Coast Guard for O&M

• DOT/RITA FY09 Funding = $4.6M Pass-through to U.S. Coast Guard for O&M Insufficient to meet O&M requirements Action to DOT to solve problem



08/05/08 12

Projected NDGPS Funding Needs:FY09 + Recapitalization

[USCG+DOT Estimates]• FY09 Shortfall

$4.6M as placeholder; insufficient for O&MShortfall ~ $0.8M

• Recapitalization (required in FY09 for any operational scenario)$3.5 – 4.0M

Equipment refresh required for ongoing operations (deferred maintenance)

Three years behind Maritime DGPS Future estimates based on completing recapitalization (proven

reduced O&M costs)

• Total Additional Need: $4.3 – 4.8M



08/05/08 13

Projected NDGPS Funding Needs: FY10 and Outyears

[USCG+DOT Estimates]

• Current System; no build-out $5.9M average annual operations and maintenance (O&M) only

• Complete Initial Operating Capability (IOC) – 8 sites $3.4 – 3.8M capital costs $6.2M annual (O&M)

• Complete Full Operating Capability (FOC) – 20 sites $19.0M additional capital costs $6.5M annual O&M
