  • Using the Global Positioning System (GPS), every point on Earth can be given its own unique address -- its latitude, longitude, and height. The U.S. Department of Defense developed GPS satellites as a strategic system in 1978. But now, anyone can gather data from them. For instance, many new cars have a GPS receiver built into them. These receivers help drivers know exactly where they are, and can help them from getting lost.

  • Among the thousands of satellites orbiting Earth are 24 that work together as the key elements of the Global Positioning System (GPS), a navigational tool of unprecedented precision. Circling the globe once every 12 hours at an altitude of more than 12,000 miles, the satellites maintain positions relative to one another that enable handheld or vehicle-mounted units to receive signals from as many as six of them at once, from virtually any point on the planet’s surface at any given time. Using signals from at least four satellites, the receivers can calculate their own location—latitude, longitude, and elevation—to within 100 feet; the more satellites the receiver has within its line of sight, the more precisely location can be determined, in some cases within 20 feet.
