GPS

GPS or Global Positioning System was designed by the U.S.military around 20-30 years ago.GPS was used in many military operations including the Operation Desert Storm in 1992.A few years later,GPS was allowed for civilian use.

What can GPS do for us ? GPS can show us our exact position on the earth anytime, no matter how bad the weather is or how far away from our destination.

As quoted from The Library of Congress's Everyday Mysteries Pages,

"GPS answers five questions simultaneously:
1. "Where am I?"
2. "Where am I going?"
3. "Where are you?"
4. "What's the best way to get there?"
5. "When will I get there?""

Everyday we drive a car.If we install a GPS receiver,we will have a clear picture and confidence in our journey.GPS helps us reach our destination effortlessly,while we can get the most of our journey.
