Global Positioning System

In ancient period world was a mystery with unrevealed secrets. The world was very big and reaching our destination was just a nightmare. Using compasses and radio maps was not very accurate to reach destination. But in today’s world after technology stepped into, life becomes easier. Technology makes the world small and compact. One such appreciated technological improvement was the GPS (Global Positioning System). This technology is used by the peoples of all ages and has placed their position in today’s market. GPS makes the world really small and any kind of object can be located in any part of the world with the help of the radio signal released by the handset you have. It has been so useful and the uses range from normal to security levels. They are mainly used to locate someone or place by entering the destination and acquiring the signal directly from the satellites to you mobile phones or to your car which helps you in navigation. These kinds of chores are done by the normal persons. GPS can also find the identity of the criminal who has been a national threat to our nation/world. It has been mainly invented for the security purpose by the United States of defence in order to protect people from terrorism. It also has many implementations in the field of Defence. Modern missiles are equipped with these GPS systems to find and hit the target accurately. The chances are very minimal in these missiles in hitting the target
