The current aids to navigation design framework needs to be updated to take into account technology advances that allow for better positioning and increased marine information.  Therefore, the Coast Guard will review the national levels of service provided to the mariner by the U.S. Aids to Navigation System (USATONS).  To determine the appropriate aids to navigation lay down, we must take a systematic and holistic approach that considers stakeholder input, environmental considerations, channel framework, user capabilities, training and carriage, available technology, and available resources.  Please assist us by providing your input to a Seacoast Waterways Analysis Management Survey.
