<VV> GPS Speed Verification on the BFGs

[mike hicks]

actually, the satellites don't calculate your speed/position or 
whatever.  They just tell your GPS unit where they are and the GPS uses 
this info from multiple satellites to figure out where YOU are and how 
fast you're going and which direction you're going in.  AND some of them 
know where things like gas stations and roads are so it can tell you how 
to get there.  Cool.

We hooked our GPS up to a laptop running MS streets and trips and 
watched ourselves drive across Indiana. Normally it's prettier out the 
window but in this case it was night and the road was almost impassable 
due to snow so it was reassuring to see we were actually making 
progress.  I find the GPS invaluable on a boat (no road signs out there)
