You must be kidding, right?
It is more of a case that cheap GPS units are keeping civilians out of his airspace.
MIL GPS usage is either hardened against jamming or has a fallback such as INS, a Pilot or map.
Read the previous notes. Lighsquared does not operate outside its licenced spectrum. If it did, then the FAA would be locking them up and throwing away the key. The problem is shortcuts in the design of gear that uses the adjacent spectrum means that they detect Lightsquared frequencies and suffer.
A suitable analogy is White Trash complaining that middle class Blacks or Asians have moved in next door. Just because you were nearby first, doesn't mean you have the right to lower other people to your standards.
And another thing, as GPS units are receivers, their makers do not pay licence fees for the spectrum they do use. Sine the US turned off significant signal degradation under Clinton, they have access to the high accuracy signal in real time. They are freeloaders watcing their gravy train slowly derail.
