Engineers map our building projects using GPS.
Cropdusters spray fields using GPS (OK - aviation).
Auto navigation use GPS.
Ocean-going shipping navigate using GPS.
The point is, every precision GPS receiver will likely be affected.
USAF General Shelton, U.S. Space Command, testified that (a) LightSquared broadcasts will affect US aircraft, and (b) he has been pressured by the White House to change his testimony.
