The Global Positioning System (GPS) is under daily attack, with over 60,000 commercial flights affected by bogus GPS signals in a single year. American GPS is at risk of being surpassed as more modern systems emerge from China, Russia, and Europe. Attacks through jamming and spoofing signals are common, especially in conflict zones, presenting risks to aviation safety and other sectors reliant on GPS. The U.S. is falling behind, with many aging GPS satellites and a lack of a civilian backup system.
