RUSSIA WARNS AIRLINES “PREPARE FOR NO GPS”: Russia’s Federal Air Transport Agency (FATA) warned national airlines of “GPS failures, degradations, and abnormal performance.” A Russian media outlet said, “Experts believe that the recommendation to prepare does not mean a ban on the use of GPS.” (AC: If Russia isn’t banning GPS access, but is warning pilots of disruptions, it is a key indicator a cyber attack may be executed against U.S. global positioning, navigation, and timing systems. The U.S. needs 25 of 33 known GPS satellites to maintain service. – D.M.)
