Clinton Unlocks GPS: Navigation Transformed for All

The error bars were eighty feet. That's how far off your civilian GPS might land you before May 1, 2000—intentionally scrambled by a Pentagon program called Selective Availability. Clinton flipped the switch on what amounted to peacetime sabotage of a public utility. Within hours, handheld devices that had been glorified compasses became precision instruments. Farmers started GPS-guided tractors. Hikers stopped getting lost. Your phone's blue dot, steady and sure, exists because someone decided accuracy shouldn't be a weapon anymore.
