The USCG Navigation Center (NAVCEN) has issued a special notice stating that, from 3 through 10 February daily from 1600 EST to 2145 EST, the GPS navigation signal in waters off Wilmington, North Carolina may be unreliable due to testing of GPS signals used by shipboard, aviation, and handheld navigation devices.

 

From Feb 03 through Feb 10, 2012, daily from 1600 EST to 2145 EST, the GPS navigation signal may be unreliable due to testing on GPS frequencies used by shipboard navigation, aviation and handheld systems. Systems that rely on GPS, such as E-911, AIS and DSC may be affected at an approximate testing center point of 33 45.00N, 77 00.00W, with an impact radius of approximately 75 NM from center point. More information is available at the Coast Guard Navigation Center website www.navcen.uscg.gov.
