Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobilephone. What do you do? Well, next time take a GPS with you. This

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. (62)You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic (電子) maps, so you know where you are. For example, in a city they can tell you the name of the street.

(63)_______.The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(計算) its position. The third part of the system is a network of ground stations. They are all over the world.
