Sept. 19, 2008 Researchers raise uncomfortable questions by showing how GPS navigation devices can be duped By Anne Ju at http://www.news.cornell.edu/stories/Sept08/GPSSpoofing.aj.html Robert Barker/University Photography Todd Humphreys, right, discusses with Paul Kintner, left, and Mark Psiaki how a GPS receiver can be "spoofed," based on the researchers' work at Cornell. Just like flat-screen televisions, cell phones and computers, global positioning system (GPS) technology is becoming something people can't imagine living without. So if such a ubiquitous system were to come under attack, would we be ready? It's an uncomfortable question, but one that a group of Cornell researchers have considered with their research into "spoofing" GPS receivers. GPS is a U.S. navigation system of more than 30 satellites circling Earth twice a day in specific orbits, transmitting signals to receivers on land, sea and in air to calculate their exact locations.
