INFORMATION
The Navigation Center (NAVCEN)
is the United States Coast Guard's Navigation Center of Excellence.
NAVCEN is located in Alexandria, VA, south of the Washington
Beltway, on the grounds of the Coast Guard Telecommunications
and Information Systems Command (TISCOM) facility.
NAVCEN operates the Navigation Information Service (NIS), the Nationwide
Differential Global Positioning System (NDGPS), and LORAN. In addition,
NAVCEN serves as the civilian interface for the Global Positioning
System and manages other navigation-related projects.
The NIS disseminates navigation and maritime safety information
to the public via the Internet and through a 24-7 watch in the NAVCEN
Operations Center. The Operations Center also staffs watches to
control 84 NDGPS sites and 24 LORAN stations across the United States.
These radionavigation systems provide reliable, precise broadcasts,
conforming to international standards to meet needs of Positioning,
Navigation, and Timing users throughout the United States.
In addition to the aforementioned missions, NAVCEN serves as the
civilian interface to the Department of Defense on GPS operations
and management.
NAVCEN also manges the Integrated ATONIS project, as well as several
other navigation-related projects.
If you are planning a visit to the Navigation Center or the Navigation
Center Detachment, please see the directions
and maps to our facilities.
The Navigation Center also maintains a "CG
Central" site for internal network users.
