How did it start?

On May 2, 2000, at approximately midnight, US EST, the Clinton administration removed a satellite scrambler that limited civilian GPS units' accuracy to 100 meters, upping their precision to within ten meters of a sought-after spot.Twenty-four satellites around the globe processed their new orders, and instantly the accuracy of GPS technology improved tenfold. Tens of thousands of GPS receivers around the world had an instant upgrade.

Now, said the White House, anyone could "precisely pinpoint their location or the location of items (such as game) left behind for later recovery."
