Before commenting on this, please read "Final Report of the GPS Spoofing Group", from Ops Group.[1] This is a group for international pilots and flight planners who have to deal with GPS spoofing routinely. They are not happy about it, for multiple reasons. Newer avionics trusts GPS too much. Bad GPS data can affect other flight systems, mis-calibrate the inertial reference systems, and even change the aircraft clock. GPS spoofing confuses the Ground Collision Avoidance System, which uses GPS position and elevation maps to report nearness to the ground. The false alarm rate is now so high that such systems are useless in parts of the world. There's a lot of this spoofing going on. Look at the maps in the report.
