  1. USCG Navigation Center &Nationwide DGPS Project Status

  2. NAVCEN Mission Statement • The Coast Guard Navigation Center promotes safe, secure, and efficient transportation on United States’ waterways by providing: • Operational and technical support for electronic navigation systems • Quality positioning, navigation and timing signalsMaritimeDGPS (USCG), NDGPS (DOT), LORAN • Accurate and timely waterways information services.

  3. Maritime Information Operations Center • 24/7 Operation of the following: • Web based Information Services. • Navigation Information Service. • GPS Civil Interface. • DGPS Monitor & Control. • LORAN Monitor & Control. • Inland River Vessel Movement Center. • Nationwide Automatic Information System (NAIS) • Long Range Identification Tracking (LRIT)

  5. Worldwide DGPS Coverage

  6. DOT NDGPS Project Status Report

  7. Prepping a Site Finding candidate property Conduct a site assessment Completion of an environmental site assessment Finding of No Significant Impact (FONSI) Completion of a real property survey Completion of the installation design plan

  8. Nationwide Single Coverage Goal • The Initial Operational Capability (IOC) goal is 99% of the continental United States with single coverage. • Currently, only 7 sites are needed to achieve IOC. Advance preparation work has been finished or in progress for the remaining 7 sites. • Bliss, ID (New Build) • Tucson, AZ (New Build) • Carlsbad, NM (New Build) • Sage Junction, ID (New Build) • Marshall, TX (New Build) • Big Lake, TX (New Build) • Patten, ME (New Build)

  9. NDGPS Construction Status

  10. IOC as of September 2009

  11. IOC Upon Completion

  12. Maritime DGPS Recap/Upgrades FC-20 FC-20: Upgraded Receivers & Antennas: L1/L2 (L2C) Geodetic Grade EC-03 Commercial Off-The-Shelf (COTS) equipment. Accuracy is observed to be 1-3 meters New system architecture is easier and less expensive to upgrade as new technologies become available. Ethernet based with remote troubleshooting capability. 16 Slide 16

  13. GPS Surface Observing System (GSOS) Network.NOAA’s Forecast Systems Lab • NOAA also uses data from our DGPS sites to continuously measure the water vapor in the atmosphere. • Greatly improves short term weather forecasts.
