Spoofing GPS

I am interested in malicious interference in vehicles and a related issue is the spoofing of sensors that are increasing in vehicles.  GPS mapping is common and has an article on how to spoof GPS.  The short version is that a signal is broadcast that overrides the true signal -- the hard part is to do it in a way that cannot be easily detected by the GPS receiver.  Doing so involves manipulating the pseudo-random noise code (PNC) that is contained in the true GPS signal whose purpose is to distinguish among the multiple GPS satellites used for positioning.
