GPS 101: What’s It All About?
If you’re one of those travelers who inevitably makes the wrong turn at the wrong time, you understand the frustration. Gas stations and fast-food joints are your friend – not for fuel, but for directions. If you decide to take a jaunt up to Quebec or Tijuana and aren’t bilingual, those wrong turns can get down-right frightening.
But, thankfully, we now have GPS, short for Global Positioning System. With this handy guide, your travels are led by more than a dozen satellites. GPS devices for cars come pre-installed in your dash or as stand-alone portable models, typically mounted by suction cup on your window. Using satellite information, which tracks your geographical location, and your car’s speed, it knows precisely where you are at any given time.
