Removal of LORAN-C Features from Nautical Products

NOAA’s Office of Coast Survey is removing all LORAN-C lattices, LORAN-C interpolators and LORAN related notes from its nautical products.  This is in response to the Department of Homeland Security’s (DHS) Appropriations Act, which states; the U.S. Coast Guard will terminate the transmission of all U.S. LORAN-C signals effective Feb. 08, 2010.  At this time, the U.S. LORAN-C signal will be unusable and permanently discontinued.

The termination of the LORAN-C signal will render the LORAN-C lattices, interpolators and notes obsolete.  The LORAN related features will be removed as new editions of products are published.  This process will commence immediately but may take several years for all products to be clear of the LORAN features.

NOAA’s Office of Coast Survey (OCS) is requesting all comments about the changes to our nautical products be sent via OCS’ inquiry page < http://nauticalcharts.noaa.gov/inquiry> Any other questions may be directed to the inquiry page or by calling NOAA’s navigation inquiry hotline: 1-888-990-NOAA (6622).
