The Global Positioning System (GPS) tells you where you are on Earth.
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?"
GPS is the only system today that can show your exact position on the Earth anytime, in any weather, no matter where you are!
