Using GPS sounds super high-tech, but in essence, its not so different from the way our ancestors used the position of the stars for navigation. If we told you your distance from a fourth city, you could estimate your location even more precisely. Effectively, a kind of Rosetta Stone for GPS triangulation mechanics. In the early years, the civilian signal was intentionally degraded for national security purposes. Finally, bowing to pressure from the companies that built the equipment, the Defense Department made GPS available for non-military purposes, with some restrictions. GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization. There are currently more than 30 satellites up, providing some margin for error. And so how do you balance that? GPS could be shut down or restricted in times of war or conflict, so nations want their own satellites to be self-sufficient. What was called "precision weapon delivery"' was if they dropped a bomb within a quarter mile of the target. We can track the taxi drivers' cab coming to pick us up.
