International GPS User Support

NAVCEN logo The U.S. Coast Guard Navigation Center (NAVCEN) is the designated point of contact within the U.S. government for GPS user support to civilians outside the United States, including international civil aviation users.

If you are a civilian user experiencing problems with the GPS satellite service (e.g., outages or interference), please report the issue to NAVCEN.
