One of the greatest inventions today is the GPS (Global Positioning System). Many many years ago, navigators searched the heavens to find a system that would show them the way to their destination. On June 26th 1993, however, the answer became as clear as day. On that date, the U.S air force launched the 24th Navastar Satellite into orbit. We have GPS companies such as Magellan and Tom Tom. Today's GPS receivers are extremely accurate, thanks to their parallel multichannel design.
My reaction to this device is that we are very lucky people to have this. It tells us exactly where to go. Back then, people didn't have advantages like this. When explorers would go out to sea to find new lands, they took a chance of being lost. This impacts the world today because military people use GPS, police officers use GPS, scientists use GPS. Without GPS troops would be lost. Without GPS policeman wouldn't know where to go when they get a call in the police department. GPS is an important aspect of life in may ways.
Here is a video explaining GPS:
