GPS Spoofing and the Potential Perils to Ships

Spoof is defined as “a hoax or swindle.” In the world of electronic networks, a spoofing attack is a situation in which one program successfully masquerades as another by falsifying data and thereby gaining an improper advantage…
It is now possible to spoof Global Positioning System (GPS) and other space-based positioning, navigation, and timing (PNT) services. To date (as far as can be determined), intentional GPS spoofing has been limited to research experiments to determine vulnerability. Iranian officials, though, claim that they were able to acquire an American stealth surveillance drone in December 2011 by transmitting false signals to the drone. The claim is almost certainly bogus, but impossible to totally disprove.
