Good point, pete, and the accuracy of military GPS is classified.

For all the tech junkies here interested in trivia, one of the main elements of GPS was invented in the 1940's, but had no practical use until GPS was invented. The atomic clock can accurately measure time in billionths of a second. So the atomic clock was a cool toy that didn't impact society for decades because no one really needed that kind of accuracy.

Then along comes GPS. No matter where you are on this planet, you are in view of at least 3 GPS satellites. These satellites can triangulate your position by measuring the response time of a beam using an atomic clock. Now, being able to accurately measure in billionths of a second has a practical use.

Now if Google can bring us this new toy, imagine what our government is capable of. Smile.
