Why are we rehashing Light Squared again? Solyndra...eh, the cost of one day of war...the important thing is where is the real birth certificate! ;-)

Are LightSquared willing to spend $20,000 to upgrade the GPS on my Skylane to a new model which does not yet exist? With that many transmitters we may experience areas where RF from multiple high power transmitters creates hot spots. In some places pieces of metal with non Ohmic bonds will create mixing products, some of which may fall directly within GPS bands. These effects have not been simulated. Who knows who the FCC is listening to - the GPS industry including millions of current users, or those who appear to have bought under the table favor. This could make Solyndra look like small change. Film at 11.
