GPS Problem Report
The Navigation Center appreciates your reports regarding service degradations, disruptions, or other incidents or anomalies. Please answer the questions below. Some fields are required for submission, but all personal data will be kept private and will only be used to contact you in the event that we need more information or if clarification is required. Please be as complete as possible when reporting an incident. Thank you!
Please read before submitting a report:
NAVCEN cannot assist you with equipment issues. We can confirm the status of the GPS constellation, determine if there is approved GPS testing in the vicinity, and request that interagency partners share correlating reports. Equipment errors are easily identified as single-device problems, such as when a vehicle GPS fails while a cell phone GPS continues to operate properly.
We recommend you follow the below steps before reporting a GPS problem.
- Reset your device by cycling power to the unit.
- Confirm the settings for your GPS unit or GPS application
- Refer to your equipment manual
- Update your equipment software or firmware and GPS mapping software
- Contact your equipment manufacturer for additional assistance
For more information, please read our GPS Frequently Asked Questions page.
If your GPS unit or others' GPS units are leading people to an incorrect address OR are otherwise leading people to an incorrect location, the problem is not likely a "GPS" problem, but rather, it is very likely a MAPPING problem.
Unfortunately, the Navigation Center cannot assist you with GPS unit mapping problems, as we do not develop, control, nor repair the mapping software contained in GPS units, including vehicle navigation systems.
To correct mapping problems such as an incorrect address, or to request a change to the address for a business or home, or to add an address, please navigate to GPS.gov to submit your corrections online: How to Report a Mapping Problem Affecting GPS Devices, Apps, and Maps.
If you are reporting a GPS issue relating to aviation (domestic or international) usage, please use the following link to report directly to the FAA (http://www.faa.gov/air_traffic/nas/gps_reports/).
The GPS Operations Center (GPSOC) at Schriever Air Force Base, Colorado, is the focal point in the Department of Defense (DOD) for operational issues and questions concerning military use of GPS. The GPSOC, part of Air Force Space Command, provides DOD and allied GPS users worldwide with anomaly reports and other information 24 hours a day, seven days a week. Please use the following link to report directly to the GPSOC (https://gps.afspc.af.mil/gps/).
