GPS









Describe how GPS works and how normal citizens have been able to use it to make their lives easier.

GPS is a global positioning satellite that is used to show the exact position on earth that you are. This system is used in many ways. Many people in a new city use rental cars. These people will probably get lost. Now in these cars there is GPS. This system allows the driver to know where they are and gives them a map of the place they are planning to visit. GPS also speaks to that person and lets them know whether they missed the street they had to turn on, or how far to their destination.
This new system can also help fisherman. Sometimes, people who fish for a living have a heard time finding good schools of fish. The GPS system is a great assistant in these situations. By using the tracking system it helps find where most of the fish are living. Now if a fisherman has a good day and wants to return to that spot another time, the GPS will save the location in its memory. Thus, allowing the fisherman to return to that exact position anytime he pleases.
Another way this system helps normal citizens is by making research a lot easier. For the scientists who study many living things, GPS makes their job a little easier. Many researchers who study whales use GPS as a tracking device. When the whale comes up to breathe the scientist shoot a radio tag on to the whale. This enable s them to track the whales life and record information. Elephants are other animals that are tracked by GPS. A collar is put on wild elephants. This collar tracks the elephant wherever it may go. From then on, scientists record information on the elephants. We can also see life from an elephant\'s point of view. The collar also records growth and biological statistics and when we need them, we track the elephant and download the research on to a computer.
