• 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

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

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
