on planes and on boats.

The Global Positioning System is very useful for everybody because the system use the power of a computer to remember the reference points (waypoints).

For some users, the GPS has replaced the road map or the roadsigns because it makes the life easier for people.

When you want to go somewhere and you don’t know the way that you have to take, you just have to

put the adress on your GPS and it will show you the good way.

AN EXAMPLE

In this situation, if you don’t have a GPS, you have to check a map or pay attention to the roadsigns, so it will take you more time to get on your destination.
