He said "E911 GPS is not really GPS. It triangulates your approximate location based on cellular tower signals. It isn't useful for anything moving... like say, navigating while driving."

It is very true E911 triangulates your position and well all know while it isnt exact, it is very close within a few feet or yards. When he says it isnt useful for anything moving or navigating you have to understand he is referencing that E911 doesnt help us when it comes to use trying to use "GPS" to navigate. If E911 triangulates then obviously if you move around it is going to continue to track you but that is only good for emergency personel and not for the average everyday user who would need GPS to do that with. So while E911 is good for emergency response personel only, GPS is only good for the consumer and owner who is trying to navigate somewhere. This makes them different yet cousins.

Very well stated. Thankyou. We are not opposed to debate on this forum. However, when one disagrees with another, it would be useful to provide some technical information as to why one may be wrong. Resorting to such vulgar statements does not impress anyone, and certainly does not get your point across. I have based my explanation on how it was explained to me by a former instructor at my college who was a retired cellular communications engineer. I, and most rational people, would consider this a fairly credible source.
