Navy warship now sails with e-navigation system

The first Navy surface warship has been certified to navigate using electronic charts.

The USS Cape St. George, based in Norfolk, Va., is using the Electronic Charting Display and Information System-Navy (ECDIS-N) with the National Geospatial-Intelligence Agency's Digital Nautical Chart (DNC) as its primary navigation system, according to an NGA release.

ECDIS-N is a charting display system that interfaces with Navy shipboard navigation systems and sensors. It lets navigators use digital chart data with interactive computers and positioning systems to control ship steering.

'ECDIS-N, or other types of geographic information systems, and DNC will provide the Navy with a previously unattainable navigational edge and tactical advantage,' said retired Air Force Lt. Gen. James R. Clapper Jr., NGA director. 'The certification of USS Cape St. George to use this technology is the wave of the future and will enable the U.S. Navy to efficiently navigate around the world.'

Since 1998 more than 5,000 paper charts have been digitized into dozens of CD-ROMS as part of a Navy initiative, working with NGA, to transition from paper charts to electronic navigation systems.
