I found this video that explains how GPS system works.
If the site does not work, you can google this: lab rats tv gps.
That is such a cool video, thanks for sharing that. I may see if we can get permission to post that on the site somewhere.
here is a tinyurl for the same link
For those who want to find out some more on how it works:
I don't see how my GPSr works inside where signal is blocked. Yet, my DirectTV (which is behind a tree) gets blocked whenever the wind blows
I didn't know that the MIO has a movie player. Do Nuvis have it? I wish I had it so when I am on the plane, I could watch it.
As that signal carries much more information that needs to be processed by the receiver, and DSS/satellite TV requires the dish, which needs to be aligned to the satellite in order to receive the signal, and they are using different frequencies - the GPS signal can propagate through some obstructions that the DSS signal can't.
