Newark Airport GBAS Vulnerable to Truckers’ GPS Jammers
GPS approaches at New Jersey airport cannot be certified until the jamming issue is resolved

GPS designers understood from the beginning that the system’s weak signals would be vulnerable to inadvertent or deliberate interference, with the threat formally recognized by the DOT’s Volpe Center in Cambridge, Mass., on Sept. 10, 2001—one day before 9/11. Since that time, the Department of Defense has run annual all-altitude tests—over the Western U.S. last month and currently over the Southeast—of the jam-resistance of military GPS equipment.

In 2009, Newark Liberty International Airport installed a Honeywell GPS ground-based augmentation system (GBAS) to enhance terminal operations, and Continental Airlines has since equipped 18 of its Boeing 737s with GBAS avionics, with the FAA providing GBAS support.
