The Global Positioning System, or GPS, is pretty amazing and chances are, it's playing a much greater role in your life than you realize. Anthony explains how GPS works and tells you about some pretty cool upgrades coming soon.
GPS http://www.gps.gov/ "Official U.S. Government information about the Global Positioning System (GPS) and related topics"
GPS is getting an $8-billion upgrade http://articles.latimes.com/2010/may/... "Without it, ATMs would stop spitting out cash, Wall Street could blunder billions of dollars in stock trades and clueless drivers would get lost."
New Satellites Could Make GPS Harder to Jam http://www.wired.com/dangerroom/2012/... "Without GPS, drones can't fly, communications networks can't function, and you don't have a chance of figuring out how to get to your Aunt Sadie's place in New Jersey. And right now, GPS is highly vulnerable because its weak signals are coming from an aging constellation of satellites."
How GPS Receivers Work http://electronics.howstuffworks.com/... "Our ancestors had to go to pretty extreme measures to keep from getting lost. They erected monumental landmarks, laboriously drafted detailed maps and learned to read the stars in the night sky."
