The GPS navigation signal may be unreliable due to testing on GPS frequencies used by shipboard navigation 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 61°14’50.8”N, 149°50’41.0”W, with apossible impact radius of 97 NM from center point. GPS testing is scheduled to be conducted August 10th, 2012, from 1600Z-2000Z (August 11th, 2012, from 0000U-0400U) and August 13th,2012 from 2200Z-2359Z (August 14th, 2012, from 0200U-0359U). More information is available at the Coast Guard Navigation Center web site WWW.NAVCEN.USCG.GOV. During this period GPS users are encouraged to report any GPS service outages that they may experience to the Navigation Information Service (NIS) by calling (703) 313-5900 or by using the NAVCEN web site to submit a GPS problem report.
