How a GPS Receiver Works 1.0

GPS (Global Positioning System) receivers tell you where you are anywhere on the planet! The Global Positioning System (GPS) is a collection of 24 earth-orbiting satellites and these satellites allow any person who owns a GPS receiver to determine his or her precise longitude, latitude and altitude anywhere on the planet. That is such an amazing capability!. For as little as $100 you can know exactly where you are and where you have been. For anyone who has ever been lost while hiking in the woods, or lost in the middle of the ocean, or lost while driving in a unfamiliar city, or lost while flying a small airplane at night, a GPS receiver is a miracle. With a GPS, you are never lost. In this edition of How Stuff Works we will discuss both what a GPS receiver can do and how it works so that you can learn more about these amazing devices.
