Seems to me there's already a couple of companies which build such spoofers, or simulators as they might be called. Pretty sure these companies also have "spoofer-resistant" receivers. I'm curious what their "patent-pending" integrity-monitoring methods include.
Next step for the bad guys is to get some of these radios and then figure out how to outwit them. Consider the extraordinary amount of resources that can be brought to bear by potential antagonists (e.g. governments of other countries).
I imagine for high reliability, other sorts of backup navigation systems will be employed alongside GPS. Maybe as simple as a camera that can view the terrain and compare it to what it should be.
