The Global Navigation Satellite System, GNSS, *IS* GPS based precision 
navigation.

It provides precise three dimensional location.  LORAN never did that.  
LORAN is *dead*.

LightSquared is NOT nor EVER was GPS.  It interferes with GPS.  It is a 
broadband wireless carrier.  Read as cell phones and the like.

The DOT, (read FAA), and DoD have pitched a fit over the interference of 
LightSquared with GPS and WAAS.  These combined systems, (WAAS is Wide 
Area Augmentation System.  It provides an airport a very fine level of 
additional GPS data allowing for Zero/Zero landing ability.)

This gives pilots the ability to fly down below MDA and put the nose 
wheel within 6" of the runway center-line.

Some folks don't get it!  LightSquared's view is that GPS "looks into 
their Bandwidth", not that it interferes with it.

They are fighting the FCCs decision!
