The U.S. Maritime Administration issued U.S. Maritime Alert 2018-004 A "Possible GPS Interference – Eastern Mediterranean Sea" on March 23 in in response to reports of GPS disruptions and interference from multiple vessels and aircraft between Cyprus and Port Said, Egypt. These reports come on the heels of multiple warnings by the same agency in 2017 of GPS disruptions in the Black Sea, primarily off the coast of Novorossiysk, Russia. These same warnings reaffirmed that GPS disruptions are a global concern and provided guidance for reporting to the U.S. Coast Guard.
Anecdotal reports abound of GPS disruptions ranging from the accidental jamming of GPS signals in San Diego by the U.S. Navy to the intentional use of GPS jammers by truckers. The Navy communications exercise inadvertently affected GPS-based devices ranging from ATM machines to air traffic control. For truckers both in the U.S. and overseas, the jamming frees them from the oversight of companies and regulators tracking routes or work hours. Use of these jammers by truckers in the vicinity of airports have affected operations both in Newark, NJ and Philadelphia, PA.
