Interesting!

I can tell you that one of the GPS satellites I worked on was turned on this week so there is another one in the mix. We received word at work this had occurred.

Thanks for the link Boyd, the link explains it in an easy to understand way. I find it incredible the FCC has gone as far as it has. I wonder what the military had to say.

This gets way beyond what I want to dig into, but as I understand, this problem with LightSquared only affects the L1 frequency and military GPS'es use L2. If you want more details, see this: http://en.wikipedia.org/wiki/Global_Positioning_System

L1 1575.42 MHz Coarse-acquisition (C/A) and encrypted precision P(Y) codes, plus the L1 civilian (L1C) and military (M) codes on future Block III satellites.

L2 1227.60 MHz P(Y) code, plus the L2C and military codes on the Block IIR-M and newer satellites.
