Nationwide Differential Global Positioning System (NDGPS) Status
• 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

National Space-Based PNT ExecCom Action
• Action: DOT complete assessment of the need for inland component of NDGPSFinal 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
• 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

Recommendations Accepted by ESG
• Ratify inland NDGPS as a national utilityReaffirm DOT sponsorshipDetermine funding required to deploy IOC/FOC
U.S. Department of Transportation
Research andInnovative TechnologyAdministration
• 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 RITA agreed to be interim program sponsor 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
