U.S. Coast Guard Navigation Center

• Chart Production and Maintenance: NAVCEN is the primary producer of nautical charts for U.S. waters. This involves surveying, data collection, analysis, and the ongoing update of electronic and paper charts to reflect changes in waterways, hazards, and navigational aids. This includes the integration of data from various sources to ensure chart accuracy.

• GPS Monitoring and Management: The center plays a key role in monitoring the performance and accuracy of the Global Positioning System (GPS) within U.S. waters. This likely involves coordinating with relevant agencies to ensure reliable GPS signal availability for mariners.

• Navigational Data Dissemination: NAVCEN ensures the timely and accurate dissemination of navigational information to mariners through various channels, including their website and likely other official government platforms. This may include Notices to Mariners, updates on chart corrections, and other relevant information.

• Data Integration and Analysis: The center integrates data from various sources, including hydrographic surveys, satellite imagery, and other geographical information systems (GIS) data, to maintain a comprehensive and up-to-date picture of the navigational environment. This complex data analysis underpins all their other functions.
