Navy Testing May Temporarily Affect GPS Signal

PORTSMOUTH, Va. – The Global Positioning Signal may be unreliable in parts of the Chesapeake Bay and the Patuxent River due to testing between Dec. 4, 2006 and March 31, 2007 between 10 p.m. and 6 a.m. Monday through Friday.

GPS systems that rely on E-911, AIS and DSC, may be affected within a 25-nautical mile radius of the Patuxent River Naval Air Station.

The Coast Guard encourages GPS users to report any service outages during the testing via the Navigation Information Service at (703) 313-5900 or by using the problem worksheet on the Coast Guard Navigation Center’s website.
